What is 1 mm as a fraction of 1 cm?

Answer 1

A millimeter is one tenth of a centimeter.

1 millimeter (mm) is 1/1000 of a meter. 1 centimeter (cm) is 1/100 of a meter.

So a millimeter is 1/10 of a centimeter, as seen on most rulers.

Answer 2

Well, honey, 1 mm is 1/10 of a cm. So, if you want that in fraction form, it's 1/10. But really, who's got time for fractions when you could just move that decimal point over one place to the left and call it a day?
