How to Convert Millimeters to Micrometers
To convert a measurement in millimeters to a measurement in micrometers, multiply the length by the following conversion ratio: 1,000 micrometers/millimeter.
Since one millimeter is equal to 1,000 micrometers, you can use this simple formula to convert:
micrometers = millimeters × 1,000
The length in micrometers is equal to the length in millimeters multiplied by 1,000.
How Many Micrometers Are in a Millimeter?
There are 1,000 micrometers in a millimeter, which is why we use this value in the formula above.
1 mm = 1,000 µm
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. 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 Micrometer?
One micrometer is equal to one-millionth (1/1,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.
The micrometer, or micrometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "micro" is the prefix for millionths, or 10-6. A micrometer is sometimes also referred to as a micron. Micrometers can be abbreviated as µm; for example, 1 micrometer can be written as 1 µm.
To get an idea of the actual physical length of a micrometer, one human hair is 40-50 µm thick, demonstrating how small this unit of measure is.

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 a combination of both values, so make sure you get the correct type for your needs.
