How to Convert Millimeters to Meters

To convert a measurement in millimeters to a measurement in meters, divide the length by the following conversion ratio: 1,000 millimeters/meter.

Since one meter is equal to 1,000 millimeters, you can use this simple formula to convert:

meters = millimeters ÷ 1,000

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

For example, here's how to convert 5,000 millimeters to meters using the formula above.

meters = (5,000 mm ÷ 1,000) = 5 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.

What Is a Millimeter?

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 ¹/_299,792,458 of a second. One millimeter is equal to 0.0393701 inches.

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 thousandths, or 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.^[1]

What Is a Meter?

According to the most recent 2019 definition, the meter is defined as the distance traveled by light in vacuum during a time interval with a duration of ¹/_299,792,458 of a second.^[2] One meter is equal to 100 centimeters, 3.28084 feet, 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.
