Frequently asked questions
How do you write a number in words?
Read the number in groups of three digits from the left, naming each group and its scale: thousand, million, billion. This converter does that for you instantly, including the decimal portion.
Can I use this for writing cheques?
Yes. Writing the amount in words is exactly what cheques, contracts and invoices require, and this is the fastest way to get it right.
Is my data sent to a server?
No. The conversion happens entirely in your browser and nothing is uploaded anywhere.
