How to Convert Meters to Millimeters

conversion scale showing meters and equivalent millimeters length values

To convert a meter measurement to a millimeter measurement, multiply the length by the conversion ratio. One meter is equal to 1,000 millimeters, so use this simple formula to convert:

millimeters = meters × 1,000

The length in millimeters is equal to the meters multiplied by 1,000.

For example, here's how to convert 5 meters to millimeters using the formula above.
5 m = (5 × 1,000) = 5,000 mm

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

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

Meters

The meter is defined as the length of the path travelled by light in vacuum during a time interval with duration of 1/299,792,458 of a second, according the most recent 2019 definition.[1] 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.

Millimeters

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.[2]

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.
