To pronounce the number 0.002, you would say “two thousandths.”
This number can be broken down as follows: the leading zero indicates that it is a decimal number, and the digits following the decimal point represent the fraction of a whole. In this case, ‘002’ means you have two parts out of a thousand. Thus, when stating the number in words, we use the term ‘thousandths’ to specify the position of the ‘2’ in relation to ‘1’. So, when you put it all together, it clearly translates to ‘two thousandths.’
