In words
How numbers become words
English names numbers in groups of three digits. The converter splits your number into those groups from the right, names each group (one to 999) and tags on the right scale word - thousand, million, billion or trillion. So 1,234,567 becomes "one million, two hundred and thirty four thousand, five hundred and sixty seven". Zeros are skipped, so 1,000,007 is simply "one million and seven".
UK vs US style
The only real difference is the word "and". British English inserts it before the final tens and units - "one hundred and five", "three thousand and twelve". American English leaves it out - "one hundred five", "three thousand twelve". Both are correct; pick the one your reader expects. For formal or legal writing in the UK, the "and" is standard.
Decimals and money
Decimals are read digit by digit after the word "point": 12.05 is "twelve point zero five". Currency mode changes this - the two digits after the point become cents or pence and are read as a normal number, so 12.05 dollars is "twelve dollars and five cents". This is exactly the wording you want when filling in a cheque, an invoice total or a contract figure, where the written amount is the one that legally counts if it disagrees with the digits.
