## How to Convert Micrometers to Millimeters

Convert micrometers to millimeters with this simple formula:

Converting a micrometer length measurement to a millimeter measurement involves multiplying the length by the conversion ratio to find the result. One micrometer is equal to 0.001 millimeters, so to convert simply multiply by 0.001.

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

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

Micrometers and millimeters are both units used to measure length.

Micrometers are a metric measurement and can be abbreviated as *µm*, for example 1 µm.
Millimeters are a metric measurement and can be abbreviated as *mm*, for example 1 mm.

Millimeter is spelled *millimetre* internationally,
and it is equal in length to .1 centimeters, 1000 micrometers, or ^{5}/_{127} inch. They are represented by the
smallest ticks on most metric rulers. To get a reference point of the size,
the thickness of a dime is 1.35mm.

A human hair is 40-50 micrometers thick or 0.000001 meters, making this a very small unit of measure.
The micrometer is often referred to as a *micron* and internationally it is spelled *micrometre*.

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.
