### 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.

### What is a Inch?

The **inch** (symbol: in or ″) is a unit of length in the British imperial and the United States customary systems of measurement. An inch in the metric system equals 2.54 cm, or 1/36 yard or 1/12 of a foot.

### How to Convert Micrometer to Inches?

To convert Micrometer to Inches, simply divide the Micrometer value by 25400.

The formula used to calculate Micrometer to Inches -

**d**_{(μm)} = **d**_{(in)} / 25400

The distance *d* in Inches (in) is equal to the distance *d* in Micrometers (μm) divided by 25400.

### How many Inches in a Micrometer

In simple terms, 1 μm is equal to 3.9370079e-05 in.

The formula used is 1/25400 = 3.9370079e-05(in)

### How many Micrometers in a Inch

1 Inch is equal to 25400 Micrometers. So we can also say that there are 25400 Micrometers in a Inch.
