## How to Convert Millimeters to Micrometers

Convert millimeters to micrometers with this simple formula:

Converting a millimeter length measurement to a micrometer measurement involves multiplying the length by the conversion ratio to find the result. One millimeter is equal to 1,000 micrometers, so to convert simply multiply by 1,000.

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

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

Millimeters and micrometers are both units used to measure length.

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

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.
