How many mm are there in a cm?

Answer 1

Because there are 100 millimeters in a centimeter, you can take the multiplicative inverse, or reciprocal of that number. To take the reciprocal of something, you reverse the numerator and denominator, so for 100 (100/1), the reciprocal would be 1/100, or 0.01.

Once again, there are 0.01 centimeters in a millimeter.

Answer 2

There are 10 millimeters in one centimeter.
