How to Convert Millimeters to Meters

conversion scale showing millimeters and equivalent meters length values

To convert a millimeter measurement to a meter measurement, multiply the length by the conversion ratio. One millimeter is equal to 0.001 meters, so use this simple formula to convert:

meters = millimeters × 0.001

The length in meters is equal to the millimeters multiplied by 0.001.

For example, here's how to convert 5 millimeters to meters using the formula above.
5 mm = (5 × 0.001) = 0.005 m

Our inch fraction calculator can add millimeters and meters together and it also automatically converts the results to US customary, imperial and SI metric values.

Millimeters and meters are both units used to measure length. Keep reading to learn more about each unit of measure.


One millimeter is equal to one-thousandth (1/1,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The millimeter, or millimetre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "milli" is the prefix for 10-3. Millimeters can be abbreviated as mm, for example 1 millimeter can be written as 1 mm.

Millimeters are often represented by the smallest ticks on most metric rulers. To get a reference point of the size, the thickness of a US dime is 1.35mm.


The meter is defined as the distance light travels in 1/299,792,458 of a second in a vacuum, according to the most recent 1983 definition. One meter is equal to 100 centimeters or 39.37 inches.

The meter, or metre, is the SI base unit for length in the metric system. Meters can be abbreviated as m, for example 1 meter can be written as 1 m.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
