How do you say .021 in words?

Answer 1

First of all as a number/decimal it should be written as '0.021'. Note the prefix zero.

In words ' Zero point zero two one'.

Answer 2

Oh, dude, you're really making me work here. So, like, you say .021 as "twenty-one thousandths." But, like, who even says that out loud? Just write it down, man, it's way easier.

Answer 3

Twenty-one thousandths.
