English Numbers 1-100 Guide: Writing, Spelling, Ordinal & More (2023)

When we start learning a language, we’re first introduced to its fundamentals: the alphabet, some basic vocabulary, and numbers.

And while our primary goal is to communicate in the language we’re learning, we tend to focus on learning tons of new words and mastering the grammar. Yet, we often leave the numbers forgotten somewhere in the depths of our memory.

However, numbers are an essential part of our everyday life. Knowing them enables you to tell the time, buy groceries, and talk about historical events.

So, in this article, we’ll stop delaying the inevitable and learn how to count to 1000 in the English language. Plus, we’ll cover the English numbers spelling, the pronunciation, and the different ways to use those numbers, from fractions to percentages and decimals.

Ready? Steady? Go!

Why learn English numbers?

English Numbers 1-100 Guide: Writing, Spelling, Ordinal & More (1)

Can you imagine a society that functions without numbers? We certainly can’t. Numbers are everywhere and are connected to everything we do.

Numbers are a part of everything from telling the time, buying groceries to distance, dates, and general conversation. They’re part of science, technology, and thus humanity and life. Let’s look at some of the main reasons why you should learn all about numerals.

Understanding dates and time

Knowing numbers is essential when scheduling business meetings, going out with friends or catching a plane. If you don’t know them, you might easily get confused when it comes to the dates and times of your business meetings, train departures, or your friend’s birthday party.

You certainly don’t want to miss any of these important events simply because you didn’t study the numbers!

Understanding prices

If you don’t know the cost of what you’re buying, you can easily spend more money than you intended. Although you can see the price of every item in the supermarket, you need to ask for it in some places.

Knowing English numerals will help you understand the prices while shopping in local markets, second-hand shops, or negotiating the cost of the product or service you want to purchase.

Understanding phone numbers

Phones are an intrinsic part of our everyday life, and so are phone numbers. We need them to make new friends, ask that cute girl or guy out, make restaurant reservations, and call important organizations or departments. If you don’t understand English numbers, you’ll easily write down the wrong phone number. This can make you miss out on new friendships, fun dates, and complicate dealing with important matters.

Learn English numbers, spelling, and pronunciation

In order to count in English, you first need to learn the numbers from 1 to 20. Once you learn the spelling and pronunciation of these numbers, it’ll help you easily count to 1000. However, learning the first 20 numbers in any language is always the hardest.

Below, we’ll give you the spelling and phonetic pronunciation of each number. Pay attention to each sound, as later on, you’ll need to put them together to form higher numbers. So, let’s break it down!

1 - 20

Tones for numbers 1-10 are simple.

However, those for 11-20 are harder because they're compound tones. It means that there are multiple sounds involved in pronouncing them. For example, to pronounce 11, you’ll say “ee-LEH-vihn.”

Check out the table below for more sounds.

100 - 1000

Let us look at how numbers 100 - 1000 are pronounced.

NumberSpellingEnglish Pronunciation
100One Hundred/wuhn-HUN-dʒrih[d]/
200Two Hundred/too-HUN-dʒrih[d]/
300Three Hundred/three-HUN-dʒrih[d]/
400Four Hundred/fohr-HUN-dʒrih[d]/
500Five Hundred/faiv-HUN-dʒrih[d]/
600Six Hundred/sihks-HUN-dʒrih[d]/
700Seven Hundred/SEH-və(ɪ)n-HUN-dʒrih[d]/
800Eight Hundred/ayt-HUN-dʒrih[d]/
900Nine Hundred/nain-HUN-dʒrih[d]/
999Nine Hundred Ninety Nine/nain-HUN-dʒrih[d] nain-dee-NAIN/
1000One Thousand/wuhn-thauz(e)nd/

How to put it all together

Let’s look at an example of a number such as four hundred fifty-five (455).

You pronounce 455 by joining four hundred (fohr-HUN-dʒrih[d]) + fifty (FIHF-dee) + five (faiv) = four hundred fifty-five (fohr-HUN-dʒrihd FIHF-dee-faiv).

Combining numbers in English may seem complex. However, once you understand the logic behind it, it becomes easier. For example, a number such as 999 is a combination of 900 + 90 + 9, so nine hundred (nain-HUN-dʒrih[d]) + ninety (nain-dee) + nine (NAIN).

Ordinal numbers in English

English has both cardinal numbers and ordinal numbers. Cardinal numbers describe quantity (one, two, three, etc.), and ordinal numbers describe position or rank in sequential order (first, second, third, etc.). More specifically, we use ordinal numbers when talking about order or placement in a sequence or series.

We use the suffix -th to form most ordinal numbers, such as fourth, fifth, or tenth. The ordinal numbers for one (first), two (second), and three (third) are exceptions.

English ordinal numbers from 21 - 99

English ordinal numbers from 21 to 99 and beyond are formed by a cardinal number for the tens and an ordinal number for the ones.

So, for example, the ordinal number for twenty-five (25) is twenty-fifth (25th). You must use a hyphen.

English ordinal numbers from 100 - 1000

Ordinals for numbers from 100 to 1000 are formed by adding the suffix -th to the word “hundred.” Let’s take a look:

100One HundredHundredth
200Two HundredTwo Hundredth

800Eight HundredEight Hundredth
900Nine HundredNine Hundredth

1000One ThousandThousandth

So, how do we use English ordinal numbers in practice? Let’s take a look at a few examples:

  1. I was third in the queue.
  2. He won his fifth football game in a row.
  3. This is my grandparents’ twentieth wedding anniversary.

How to say decimal numbers

Decimals are numbers with decimal points - in other words, numbers that aren't whole, such as 0.00201, 0.03, 0.75, or 3.14159. Decimal numbers are spoken by listing each individual digit:

  • 0.00201 = zero point zero zero two zero one
  • 0.03 = zero point zero three
  • 0.75 = zero point seven five (in this case, you can also say “zero point seventy-five”)
  • 3.14159 = three point one four one five nine

The zero before the point can sometimes be omitted. So instead of saying “zero point zero three” (0.03), you can say “point zero three.”

Written decimalHow to say it
0.1Zero point one
0.5Zero point five
0.75Zero point seven five, or zero point seventy-five
0.8Zero point eight
1.414One point four one four
2.25Two point two five, or two point twenty-five
3.001Three point zero zero one
3.14159Three point one four one five nine
9.87Nine point eight seven, or nine point eighty-seven
10.546Ten point five four six

So, how do we use decimal numbers in a sentence? Let’s see a few examples:

  1. Over the last week, there was a 0.03% (zero point zero three percent) rise in gasoline prices.
  2. The distance is 0.75 (zero point seventy-five) miles.

How do you read sums of money in different currencies?

English Numbers 1-100 Guide: Writing, Spelling, Ordinal & More (2)

If the decimal refers to sums of money, it’ll be pronounced differently. So, for example, $9.99 will be pronounced as “nine, ninety-nine” instead of “nine point nine nine.” This is because it’s a shortcut that stands for nine dollars and ninety-nine cents.

In a sentence, it’d look like this:

  1. A gallon of milk costs $3.88 (three, eighty-eight, or three dollars and eighty-eight cents).
  2. Today, one euro can give you $1.11 (one dollar and eleven cents).
Sum of MoneySpoken
$2Two dollars
€5.40Five forty, or five euros and forty cents
£13.5Thirteen fifty, or thirteen pounds and fifty cents
¥55.99Fifty-five, ninety-nine yens
8 złEight złoty
€99.99Ninety-nine ninety-nine, or ninety-nine euros and ninety-nine cents
$225.75Two hundred twenty-five dollars and seventy-five cents
$9.99Nine ninety-nine, or nine dollars and ninety-nine cents
£7.15Seven fifteen, or seven pounds and fifteen cents
$25.50Twenty-five fifty, or twenty-five dollars and fifty cents
€2.20Two twenty, or two euros and twenty cents

Fractions in English

To form a fraction in English, write the numerator (the number on top of the fraction), followed by the denominator (the number on the bottom).

To pronounce English fractions, first, say the numerator as a cardinal number. Then, say the denominator as an ordinal number. For example:

  • 1/2 = one half (this is an exception, and we don't say "one second")
  • 1/3 = one third
  • 1/4 = one fourth, or one quarter

If the numerator is more than one, the denominator will be pronounced like a plural ordinal number. For example, 2/3 = two thirds or 2/5 = two fifths.

Written FractionSpoken
1/2Half or one half
1/6One sixth
2/5Two fifths
3/4Three quarters
4/7Four sevenths
7/8Seven eighths

Fractions are very useful in our everyday life. We use them to describe a part of something, for example,

  1. I ate half the pack of cookies yesterday!
  2. There’s still three-quarters of my birthday cake left.
  3. He already drank two-thirds of the Coca-Cola bottle.

Measurements in English

Measurements in English follow either a metric or an imperial system. For example, the US uses the imperial system and measures temperature in Fahrenheit instead of Celsius.

Here are some common measurements in English with their symbols:

Metric system:

  • millimetre (mm)
  • centimetre (cm)
  • metre (m)
  • kilometre (km)
  • gram (g)
  • kilogram (kg)

Imperial system:

  • inch (in)
  • foot (ft)
  • yard (yd)
  • mile (mi)
  • ounce (oz)
  • pound (lb)

To pronounce measurements, use cardinal numbers. Take a look at the following table.

Written MeasurementsSpoken
5LFive liters
10mTen meters
60km/hrSixty kilometers per hour
73lbSeventy-three pounds
50kgFifty kilograms
1.20kgOne kilogram and twenty grams
0.75kmZero point seventy-five kilometers, or 750 meters

Let’s see how to use the English measurements in sentences:

  1. The distance between New York and San Francisco is 4129.06km (four thousand hundred twenty-nine point zero six kilometers).
  2. I used to weigh 88kg (eighty-eight kilograms).
  3. She lost over 20lb (twenty pounds) for her wedding day.

Percentages in English

We use percentages to describe parts of a whole. For example, if we say that our pizza is 50% cheese, that means that half of the pizza is cheese. We also use percentages to compare one thing to another. For example, if we say that our pizza is 50% cheaper than the competition, we are comparing our price to the price of other pizzas.

So, how do you pronounce percentages? Just say the number and add the word “percent” after it! Take a look at the examples:

Number PercentageSpoken or Written Percentage
1%One Percent
10%Ten Percent
25%Twenty-five Percent
0.5%Zero point five Percent
99%Ninety-nine Percent

Here’s how to use percentages in real-life sentences:

  1. 45% of people have blue eyes.
  2. 95% of the world's population aren’t English native speakers.
  3. The enrollment rate was just 15%.

English numbers songs

The following are different numbers songs that learners can use to learn how to count in English and remember all the numbers, great for both kids and adults (hey,a catchy tune is a catchy tune!):

Number songs 1-10

1, 2, 3, 4, 5 Once I Caught a Fish Alive by Nursery Rhymes and Kids Songs

Numbers songs 1-20 - Twenty Green Bottles

And if you want to go even further, 100, 500, even 1000?You can use these songs to count up and down to as many bottles as you desireby switching the words, for example:

A thousand green bottles
Hanging on the wall
A thousand green bottles
Hanging on the wall
And if one green bottle
Should accidentally fall
There'll be nine hundred ninety-nine green bottles
Hanging on the wall

Please havean extra round of applause from us if you go for the big numbers - that's commitment.
