Why we still write amounts in words
Spelling out a figure isn't an old-fashioned formality: it's a safeguard. On a cheque, a contract or an invoice, the amount written in words stops someone adding a zero or shifting a decimal point. If the figure and the words disagree, on many legal documents the words prevail, precisely because they're harder to tamper with.
The rules people get wrong
English numbers have a few habits that catch people out. Numbers from 21 to 99 are hyphenated: "twenty-one", "forty-five", not "twenty one". In British usage, "and" goes before the tens or units within the hundreds: "one hundred and two", "two thousand and fifty". And there's no "and" between thousands and hundreds when the hundreds are present: "one thousand two hundred", not "one thousand and two hundred".
Hundreds, thousands and millions
Each group of three digits is read on its own and then named: 1,250,000 is "one million, two hundred and fifty thousand". Unlike some languages, the scale words stay singular even after a number: "three hundred", not "three hundreds". Getting this right matters on a document where the figure also has to appear fully in words, and it's easy to slip when writing a long amount by hand. The tool does it for you.
Handy for amounts with pence or cents
On cheques and receipts it's common to write the whole part in words and the fraction separately, in the style "… pounds and 50 pence" or "… and 50/100". Having the conversion done instantly saves time for anyone filling in documents where the amount must also be spelled out in full.
