What is a Micrometer?

Definition

A micrometer, also known as a micron, is a unit of length equal to one millionth of a meter (1×10⁻⁶ m).

History

The term micron was officially accepted between 1879 and 1967 but later deprecated. Micrometer is the current standard term.

Common Uses

  • Measuring microscopic objects (e.g., bacteria, cells)
  • Precision engineering tolerances
  • Semiconductor manufacturing

Unit FAQs

Is a micrometer the same as a micron?

Yes, 'micron' is an older, deprecated name for the micrometer (μm). Both refer to one millionth of a meter.

How many micrometers are in a millimeter?

There are 1,000 micrometers (μm) in 1 millimeter (mm).

What are some examples of things measured in micrometers?

Examples include the diameter of human hair (around 50-100 μm), bacteria (typically 1-10 μm), and the thickness of plastic bags.
