READING DECIMALS

Read decimals aloud in English by pronouncing the decimal point as "point", then read each digit individually. Money is not read this way.

Written	Said
0.5	point five
0.25	point two five
0.73	point seven three
0.05	point zero five
0.6529	point six five two nine
2.95	two point nine five

READING FRACTIONS

Read fractions using the cardinal number for the numerator and the ordinal number for the denominator, making the ordinal number plural if the numerator is larger than 1. This applies to all numbers except for the number 2, which is read "half" when it is the denominator, and "halves" if there is more than one.

Written	Said
1/3	one third
3/4	three fourths
5/6	five sixths
1/2	one half
3/2	three halves

PRONOUNCING PERCENTAGES

Percentages are easy to read aloud in English. Just say the number and then add the word "percent".

Written	Pronounced
5%	five percent
25%	twenty-five percent
36.25%	thirty-six point two five percent
100%	one hundred percent
400%	four hundred percent

READING SUMS OF MONEY

To read a sum of money, first read the whole number, then add the currency name. If there is a decimal, follow with the decimal pronounced as a whole number, and if coinage has a name in the currency, add that word at the end. Note that normal decimals are not read in this way. These rules only apply to currency.

Written	Spoken
25$	twenty-five dollars
52€	fifty-two euros
140₤	one hundred and forty pounds
$43.25	forty-three dollars and twenty-five cents (shortened to "forty-three twenty-five"  in everyday speech)
€12.66	twelve euros sixty-six
₤10.50	ten pounds fifty

PRONOUNCING MEASUREMENTS

Just read out the number, followed by the unit of measurement, which will often be abbreviated in the written form.

Written	Spoken
60m	sixty meters
25km/h	twenty-five kilometers per hour
11ft	eleven feet
2L	two liters
3tbsp	three tablespoons
1tsp	one teaspoon

PRONOUNCING YEARS

Reading years in English is relatively complicated. In general, when the year is a four digit number, read the first two digits as a whole number, then the second two digits as another whole number. There are a few exceptions to this rule. Years that are within the first 100 years of a new millenium can be read as whole numbers even though they have four digits, or they can be read as two two-digit numbers. Millennia are always read as whole numbers because they would be difficult to pronounce otherwise. New centuries are read as whole numbers of hundreds. We do not use the word "thousand", at least not for reading years within the past 1000 years.

Years that have just three digits can be read as a three digit number, or as a one digit number followed by a two-digit number. Years that are a two digit number are read as a whole number. You can precede any year by the words "the year" to make your meaning clear, and this is common for two and three digit years. Years before the year 0 are followed by BC, pronounced as two letters of the alphabet.

Interestingly, these rules apply to reading street addresses as well.

Written	Spoken
2014	twenty fourteen or two thousand fourteen
2008	two thousand eight
2000	two thousand
1944	nineteen forty-four
1908	nineteen o eight
1900	nineteen hundred
1600	sixteen hundred
1256	twelve fifty-six
1006	ten o six
866	eight hundred sixty-six or eight sixty-six
25	twenty-five
3000 BC	three thousand BC
3250 BC	thirty two fifty BC

HOW TO SAY 0

There are several ways to pronounce the number 0, used in different contexts. Unfortunately, usage varies between different English-speaking countries. These pronunciations apply to American English.

Pronunciation	Usage
zero	Used to read the number by itself, in reading decimals, percentages, and phone numbers, and in some fixed expressions.
o (the letter name)	Used to read years, addresses, times and temperatures
nil	Used to report sports scores
nought	Not used in the USA
