Number to Words Converter

Write the dollars in words, add "and", then the cents as a fraction of 100: $1,250.50 becomes One thousand two hundred fifty and 50/100. Write 00/100 when there are no cents, start at the far left of the line, and draw a line to the end so nothing can be added.

Yes, but only the compound numbers from twenty-one to ninety-nine, such as forty-two and sixty-seven. Nothing else takes a hyphen: it is two hundred, not two-hundred, and three thousand, not three-thousand. This rule is the same in American and British English and in the Chicago Manual of Style.

Both are correct, in different countries. British English puts "and" before the last tens and units, so 105 is one hundred and five and 1,005 is one thousand and five. American English usually leaves it out. On a US check, "and" is kept for the cents, which avoids confusion.

Forty. Four keeps its u in fourteen, but forty drops it, and fourty is one of the most common spelling mistakes in written numbers. Type fourty-two into the converter and it returns 42 with a note that the correct spelling is forty-two. Ninety, ninth and twelfth are the other frequent traps.

Type the words instead of digits and the converter switches direction on its own: one thousand two hundred fifty becomes 1250, with or without hyphens and with or without "and". It also reads ordinals like twenty-first, decimals like three point one four, years like nineteen eighty-four, and mixes like 5 million or 1.5 billion.

Only the last word changes. One, two and three become first, second and third, five becomes fifth, eight becomes eighth, nine becomes ninth and twelve becomes twelfth. Words ending in y switch to ieth, so forty becomes fortieth, and every other word adds th, as in one hundred twenty-fourth.

Years are usually read in pairs of digits: 1984 is nineteen eighty-four and 2024 is twenty twenty-four. A zero in the middle is read as "oh", so 1905 is nineteen oh-five. The years 2000 to 2009 are the exception, normally said as two thousand five, and round centuries become nineteen hundred.

They are the large-number names of the Indian numbering system. One lakh is 100,000, written 1,00,000, and one crore is 10 million, written 1,00,00,000. After the first thousand, digits are grouped in twos, so 12,34,56,789 reads twelve crore thirty-four lakh fifty-six thousand seven hundred eighty-nine.

Today, in both American and British English, a billion is a thousand million, 10 to the 9th. That is the short scale. Older British texts and several European languages use the long scale, where a billion is a million million. The converter shows the long-scale wording separately for numbers that big.

Up to 66 digits, which reaches the vigintillions, 10 to the 63rd, the largest number with a standard English name used here. The digits are read as text rather than as a computer number, so even very long numbers and decimals come out exact, with no rounding.
