Convert Millimeters to Micrometers
Learn How to Convert Millimeters to Micrometers Using our Conversion Formula
Converting a millimeter length measurement to a micrometer measurement involves multiplying your length by the conversion ratio to find the result. A millimeter is equal to 1000 micrometers, so to convert simply multiply by 1000.
For example, 5mm = (5 × 1000) = 5,000µm.
Our inch fraction calculator can add millimeters and micrometers together and it also automatically converts the results to both imperial and metric values.
Millimeters and micrometers are both units used to measure length. Learn more about length and find more length measurement conversion calculators. A millimeter is a metric measurement and can be abbreviated as mm, for example 1mm. A micrometer is a metric measurement and can be abbreviated as µm, for example 1µm.

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.
