About These Units

Millimeters and Meters are linked by one constant: 0.001. Multiply your Millimeters figure by it and you have the answer in Meters — for example 10 Millimeters becomes 0.01 Meters. The calculator above handles decimals and large numbers alike; the reference table lists the values people look up most.

Millimeters and Meters measure the same physical quantity but belong to different scales, so moving a figure from Millimeters into Meters — 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

Introduced as part of the decimal metric system in the late 1700s.

About Meters

The meter (m) is the SI base unit of length, originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole, now defined by the speed of light in vacuum.

History

Adopted internationally in 1889 and now used by nearly every country in the world.
