The name one milliard is almost never seen in the USA and is rarely seen in the UK except in older documents. However it is frequently seen in Continental Europe

Using one billion for 1000000000 (109) has been common in the US for some time. In 1974, Prime Minister Harold Wilson announced in the House of Commons that the official meaning of one billion would change to 1000000000 (109) in conformity with usage in the US

Prior to 1974, one billion in the UK was sometimes referred to 109 and sometimes 1012. Many English speaking peoples of the Commonwealth equate one billion with 1012

Regarding regional English language variations

There exist many of variations of the names of numbers in the English language. Examples include this such as "zero" vs. "naught", "thousand million" vs. "millard", "one thousand two hundred" vs. "twelve hundred", "two hundred and forty" vs. "two hundred forty", etc. English is a multifaceted language. English spelling and grammar of New Zealand, Canada, Australia, U.K., U.S.A., just to name a few places will differ. Even the output of digits can differ among English speaking countries. For example: 123,456.789 vs. 123 456.789

Numbers in Text

As a general rule, spell out numbers from 0 to 10, and use numerals to express numbers 11 and greater

She and her three cousins sent out 125 Christmas cards

However, always use numerals to express numbers used with fractions, numbers followed by units of measurement, money amounts, dates, percentages, and decimals

Consistent Treatment of Like Numbers

If a list includes numbers greater than and less than 11, express all numbers in the list as numerals

Incorrect: The box contains four books, 14 folders, two staplers, and 23 pencils.
Correct: The box contains 4 books, 14 folders, 2 staplers, and 23 pencils

Numbers at the Beginning of a Sentence

Always spell out a number at the beginning of a sentence. If the number is unwieldy when expressed in words, rephrase the sentence so that the number appears in the middle or at the end

Incorrect: 1,457 people attended the concert.
Acceptable: One thousand four hundred and fifty-seven people attended the concert.
Better: The concert was attended by 1,457 people

Commas in Numbers

If a number has five or more digits, insert a comma after every three digits, counting from the right

Incorrect: 10650; 5188990
Correct: 10,650; 5,188,900

However, do not use commas in numbers of four digits, street numbers, temperatures, telephone numbers, or ZIP codes

Ordinal Numbers

Add the suffixes nd, rd, and th to numerals greater than ten to create their ordinal form.

Julie placed 12th; James, 23rd; and Patricia, 32nd

Millions, Billions, Etc

In text, express rounded numbers greater than 1 million with a numeral followed by a word such as million or billion.

Incorrect: Of the nearly 23,000,000 people in the country, only 4,567,988 live in cities
Correct: Of the nearly 23 million people in the country, only 4,567,988 live in cities

Ranges of Numbers

Use the preposition pair from…to to express a range of numbers if the range includes the numbers cited. Use between…and if the range does not include them

Pick a whole number from 11 to 14. [meaning 11, 12, 13, and 14]I
Pick a whole number between 11 and 14. [meaning 12 and 13]I

You may also use an en dash in place of the word to to indicate a range. If you use an en dash, however, do not add the word from in front of the first number

Incorrect: the pages from 118–276
Correct: the pages from 118 to 276
Or: the pages 118–276
