Convert micrometer to millimeter
Please provide values below to convert micrometer [µm] to millimeter [mm], or Convert millimeter to micrometer.
1 µm = 0.001 mm. To convert micrometer to millimeter, multiply the value by 0.001; to go the other way, divide by it (1 mm = 1000 µm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µm = 0.001 mm
- 1 mm = 1000 µm
- 10 µm = 0.01 mm
- 100 µm = 0.1 mm
How to Convert Micrometer to Millimeter
1 µm = 0.001 mm
Example: convert 15 µm to mm:
15 µm = 15 × 0.001 mm = 0.015 mm

Micrometer
A micrometer, also known as a micron, is a unit of length equal to one-millionth of a meter.
History/Origin
The term "micron" and the symbol µ were officially declared obsolete by the General Conference on Weights and Measures (CGPM) in 1967, and "micrometer" became the official term.
Current Use
The micrometer is a common unit for measuring the wavelength of infrared radiation, as well as the size of biological cells and bacteria. It is also widely used in technology and engineering.
Millimeter
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter.
History/Origin
The prefix "milli-" comes from the Latin word "mille," meaning thousand. The millimeter was part of the original metric system adopted in France in 1795.
Current Use
The millimeter is widely used in engineering and manufacturing for high-precision measurements. It is also a common unit in construction and for measuring small objects.
Frequently Asked Questions
What is 1 micrometer in millimeter?
1 micrometer (µm) = 0.001 millimeter (mm).
How do you convert micrometer to millimeter?
Multiply the micrometer value by 0.001. For example, 25 µm × 0.001 = 0.025 mm.
What is 10 micrometer in millimeter?
10 µm = 0.01 mm.
Which unit is larger, the micrometer or the millimeter?
The millimeter is the larger unit: 1 µm equals only 0.001 mm.
