    How many Millimeters in a Meter?

Two of the most used metric system units are meters (m) and millimeters (mm). They both measure length, but differ in magnitude. According to the treaty signed by the International System of Units (SI) in 1959, 1,000 millimeters equal 1 meter.

    Difference between Millimeters and Meters

As we have already established, the millimeter is only 0.001 of a meter. This is also indicated by its prefix ‘milli’, which comes from Latin and means ‘1/1,000 of’.

The mm measures really small changes, and is therefore a preferred unit when it comes to tasks that rely on accuracy. Engineering, mechanics, scientific experiment are all based on millimetric calculations.

On the other hand, the meter is the basic measurement unit according to the SI. Its definitions have varied throughout the years, and the latest one reads that one meter is equal to the path travelled by light in 1/299,792,458 seconds in vacuum.

Another one of its modern clarifications is in connection to a specific number of wavelengths of a certain emission line of krypton-86.

    How to convert Millimeters to Meters

In order to convert units adopted by the metric system, you need to calculate multiples of 10. One way for you to transform millimeters to meters is simply move the decimal point three places to the left. You’ll receive the same result if you go by this formula:

mm / 1,000 = m.

Mm to m conversion example

Sample task: convert 1500 millimeters to meters. Solution:

mm / 1000 = m
1500 mm / 1,000 = 1.50 m
End result:
1500 mm is equal to 1.50 m
