How do you write thirty thousandths of an inch?

Answer 1

0.03

Answer 2

0.030 inch; or 0.03 inch, three hundredths of an inch, to which it is equivalent.

Think 30 X 1/1000; cancel a zero top and bottom to get 3/100, three hundredths

(The first digit to the right of the decimal point is the tenths place, next right is the hundredths, and third right is the thousandths place. On the right side of the decimal, your number has to end in the named place, so '30' ends with its zero in the thousandths place. Thirty thousandths is 0.030. Three thousandths is 0.003 .)
