# Fermi to Micrometer Converter

## Fermi

What is the fermi?

A **fermi** is equivalent to a femtometer. It is the older non–SI measurement unit of length. The femtometer is a unit of length. It can be abbreviated as fm. It is used in the SI system of units. It equals 1×10^{−15} meters. It is used mainly in nuclear physics.

## Micrometer

*What is meter?*

In 1793, The distance from the equator to the North Pole was measured and divided by 10 million. The result of the previous process was called as a meter.

Nowadays, meter or metre is the base unit of length in the International System of Units (SI).

**Meter** or **metre** is a metric measurement slightly longer than a yard. It is the base unit of length in the International System of Units (SI). Distance measures length. For example, the distance of a road is how long the road is.

Meter is used as a measure of distance across the globe. Distance expresses the length. For example, the distance of a road is how long the road is.

However most of countries use meter to measure length, US is the primary exception which is using imperial system.

*What is micrometer?*

Micrometer is a small tiny fraction of the meter. It equals to 1×10^{−6} meter. It is symbolized by “μ”.

Micrometer is used for the following measurement:

- Wavelengths of infrared radiation.
- Sizes of biological cellsand bacteria.
- Grading wool by the diameter of the fibers.
