Both millimeter (mm) and meter (m) are units of length in the Metric System. So when you convert between these units, you are performing a conversion between two units within the Metric System.

Let's take a closer look at the conversion formulas so that you can do these conversions yourself either with a calculator or with an old-fashioned pencil and paper.

The formula to convert from mm to m is:

m = mm x 0.001

The formula to convert from m to mm is:

mm = m x 1,000

Next, let's look at some examples showing the work and calculations that are involved in converting between milimeters (mm) and meters (m).

Task: Convert 1500 millimeters to meters (show work)Formula:mm x 0.001 = mCalculations:1,500 mm x 0.001 = 1.5 mResult:1,500 mm is equal to 1.5 m

Task: Convert 3.6 meters to millimeters (show work)Formula:m x 1,000 = mmCalculations:3.6 m x 1,000 = 3,600 mmResult:3.6 m is equal to 3,600 mm

For quick reference purposes, below are conversion tables that you can use to convert from mm to m, and m to mm.
