About These Units

Millimeters and Centimeters are linked by one constant: 0.1. Multiply your Millimeters figure by it and you have the answer in Centimeters — for example 10 Millimeters becomes 1 Centimeters. The calculator above handles decimals and large numbers alike; the reference table lists the values people look up most.

Millimeters and Centimeters measure the same physical quantity but belong to different scales, so moving a figure from Millimeters into Centimeters — or back again — is a routine step whenever specifications, prices, or measurements cross between the two systems.

About Millimeters

The millimeter (mm) is 1/1,000 of a meter, used wherever fine precision matters.

History
