# Micron vs. Micrometer: What's the Difference?

Edited by Aimie Carlson || By Janet White || Updated on September 29, 2023
"Micron" is a unit of length equivalent to one-millionth of a meter, while "Micrometer" can either refer to the same unit of length or to a device used for precise measurements.

## Key Differences

"Micron" specifically refers to a unit of length that is one-millionth of a meter. "Micrometer," on the other hand, can be a unit of length that is synonymous with "Micron" or a precision measuring instrument.
Both "Micron" and "Micrometer" as units of measurement are often used in science and engineering for specifying very small dimensions. "Micrometer" as an instrument is commonly used in various fields for highly accurate measurements.
"Micron" is exclusively a noun and cannot function as a verb. "Micrometer," however, while primarily a noun, can be used more flexibly, especially when referring to the measuring instrument, as in "to micrometer a sample."
"Micron" is primarily employed in the metric system. "Micrometer," when used as an instrument, is a part of both the metric and the imperial systems and can measure dimensions usually in either micrometers or inches.
"Micron" is generally not confused with other terms. "Micrometer," however, often requires additional context to distinguish between its two primary meanings: the unit of measurement or the measuring instrument.

#### Micron

A unit of length equal to one thousandth (10-3) of a millimeter or one millionth (10-6) of a meter. Also called micrometer.

#### Micrometer

A device for measuring very small distances, objects, or angles, especially one based on the rotation of a finely threaded screw.

#### Micron

(physics) The thousandth part of one millimeter; the millionth part of a meter.
