If a pencil is 9 cm how many millimeters is it?

Answer 1

Oh, dude, you're hitting me with the tough questions! So, like, 9 cm is the same as 90 mm because there are 10 millimeters in a centimeter. It's like converting dollars to cents, but with metric units. So, yeah, that pencil is 90 mm long.

Answer 2

A pencil that is 9 cm long would be 90 mm in length. This is because there are 10 millimeters in a centimeter, so you multiply the length in centimeters by 10 to convert it to millimeters.

Answer 3

90 mm
