Expressing Numbers in English

:: If a number is in the range 21 to 99, and the second digit is not zero, we should write the number as two words separated by a hyphen:
25   twenty-five
57   fifty-seven
89   eighty-nine

:: Numbers over 100 are generally written in figures. However if you want to say them aloud or want to write them in words rather than figures you put 'and' in front of the number expressed by the last two figures. For example:
203      two hundred and three             (AmE: two hundred three)
622      six hundred and twenty-two     (AmE: six hundred twenty-two)

:: Numbers between 1000 and 1,000,000 is usually said or written in words as:
1,803    one thousand, eight hundred and three            (AmE: one thousand, eight hundred three)
1,963    one thousand, nine hundred and sixty-three     (AmE: one thousand, nine hundred sixty-three)
2,840    two thousand, eight hundred and forty            (AmE: two thousand, eight hundred forty)

Four-figure numbers ending in 00 can also be said or written as a number of hundreds. For example, 1800 can be said or written as "eighteen hundred"

:: If the number 1963 is being used to identify something, it is said as "one nine six three". We always say each figure separately like this with telephone numbers. If a telephone number contains a double number, we use the word "double":
561 6603    five six one [pause] double six 'oh' three  (AmE: five six one [pause] six six 'oh' three)

:: Saying years. We normally say a year in two parts. In the case of years ending in "00", we say the second part in "hundred":
1058   ten fifty-eight
1706   seventeen hundred and six (or 'seventeen oh six')
1865   eighteen sixty-five
1900   nineteen hundred

There are two ways of saying years ending in "01" to "09" before 2000. For example: "1901" can be said as "nineteen oh one" or "nineteen hundred and one". The year 2000 is read "two thousand", 2006 "two thousand and six" (AmE: two thousand six). Post-2010 dates are often said as normal (2010 would be "twenty ten").

:: Flight numbers. We pronounce a flight number in two parts or digit-by-digit. For example:
110      one ten (or 'one one oh')
1248    twelve forty-eight
2503    twenty-five oh three
3050    three oh five oh (or 'three zero five zero', 'thirty fifty')

:: Expressing millions.
1,412,605        one million four hundred (and) twelve thousand six hundred (and) five
2,760,300        two million seven hundred (and) sixty thousand three hundred

Remember: The British use 'and' before tens and ones but the Americans usually leave the 'and' out.

Ways of expressing the number 0

0 = nil
in football and other sports, for scores of 0 (AmE: zero or nothing)

0 = love
in tennis

0 = zero
in temperatures to refer to freezing point (0° Celsius, 0° Fahrenheit)

0 = nought
in mathematics (AmE: zero)

0 = oh
for telephone numbers

0 = oh (or zero)
for flight numbers

1. We use zero to express some numerical values such as temperatures, taxes, and interest rates.
2. We can pronounce "0" like the letter "o", when we are reading out numbers figure by figure (e. g. telephone number, flight number, credit card number, etc.)

Fractional numbers

½ a half 0.5 British English nought point five
American English zero point five
2½ two and a half 2.5 two point five
¼ a quarter 0.25 British English nought point two five
American English zero point two five
¾ three quarters
American English also three fourths
0.75 British English nought point seven five
American English zero point seven five

Writing full stops and commas in numbers

Use a full stop (.) to separate the main part of a number from the decimal part. 3.062 means 'three point nought six two'.

Say point to refer to the full stop. You can use a comma (,) in large numbers to separate the hundreds, thousands, and millions. 3,062 means 'three thousand and sixty-two'. In British English, spaces are sometimes used instead of commas (3 062).

Remember: Speakers of some other languages use (,) and (.) in the opposite way - the commas for the decimals and the points for thousands, millions, etc.
