Convert Millimeters (mm) to Micrometers (μm)

Please provide the values below to convert from Millimeter (mm) to Micrometers (μm) and vice versa.

What is a Millimeter?

The Millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one-thousandth of a meter, which is the SI base unit of length. Therefore, there are one thousand millimeters in a meter and ten millimeters in a centimeter.

What is a Micrometer?

The Micrometre (SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length equalling 1×10−6 meter (SI standard prefix "micro-" = 10−6); that is, one-millionth of a meter (or one-thousandth of a millimeter, 0.001 mm, or about 0.00004 inches).

A micrometer is a standard unit of measurement used to measure wavelengths of infrared radiations, sizes of biological cells and bacteria, and for grading wool by the diameter of the fibers.

The width of a single human hair ranges from approximately 20 to 200 μm. The longest human chromosome, chromosome 1, is approximately 10 μm in length.

How to Convert Millimeter to Micrometers?

To convert Millimeter to Micrometers, simply multiply the Millimeter value by 1000.

The formula used to calculate Millimeter to Micrometers -

d(mm) = d(μm) * 1000

The distance d in Micrometers (μm) is equal to the distance d in Millimeters (mm) multiplied by 1000.

How many Micrometers in a Millimeter

In simple terms, 1 mm is equal to 1000 μm.

The formula used is 1*1000 = 1000(μm)

How many Millimeters in a Micrometer

1 Micrometer is equal to 0.001 Millimeters. So we can also say that there are 0.001 Millimeters in a Micrometer.
