# Micrometers (µm) to Inches (in) Converter

This length unit converter dynamically calculates a value you enter in micrometers (µm) and converts it to its equivalent value in inches (in). A micrometer is also known as a micron.

## How many micrometers (µm) are in an inch (in)? What is the formula for how to convert micrometers to inches (µm to in)?

1 micrometer (µm) = 0.000039370078740157 inch (in)
So we can say that there is 0.000039370078740157 inch in 1 micrometer.
This means that the multiplication conversion factor to convert a quantity expressed in a micrometer unit of measurement to an equivalent quantity expressed in an inch unit of measurement is 0.000039370078740157.

Inversely (or reciprocally),

1 inch (in) = 25,400 micrometers (µm)
So we can say that there is 25,400 micrometers in 1 inch.
This means that the division conversion factor to convert a quantity expressed in a micrometer unit of measurement to an equivalent quantity expressed in an inch unit of measurement is 25,400.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in micrometers to an equivalent quantity of length expressed in inches (µm to in). Both formulas will yield the same result. The formulas are:

`in = µm × 0.000039370078740157    → This is the formula based on the multiplication conversion factor.`

and

`in = µm ÷ 25,400    → This is the formula based on the division conversion factor.`

For example, if you have a length of 65,000 micrometers that you want to convert to inches, you would use either of the two formulas as follows:

`in = 65,000 µm × 0.000039370078740157 = 2.55905511811 in`
`in = 65,000 µm ÷ 25,400 = 2.55905511811 in`

So, the result is the same using either formula, which is 2.55905511811 inches.

## Micrometers to inches (µm to in) conversion chart

To save you time and effort spent on having to perform manual calculations or look up conversion formulas every time a conversion from micrometers to inches is needed, here is a micrometers-to-inches conversion chart for your quick and easy reference. This conversion chart (or conversion table) shows common measurement values of length in micrometers and their equivalent measurement values in inches. These equivalent measurement values may be rounded off to 1 or 2 decimal places when it is mathematically expedient for everyday applications.

## What is a micrometer (µm)?

Definition of micrometer: A micrometer, also known as a micron, is a unit of length in the International System of Units (SI). It is equal to one millionth of a meter (10^-6 m). It is frequently used in scientific and industrial applications to measure very small distances such as cells, bacteria, and fine particles.

The term “micrometer” (µm) is the technically correct and preferred term according to the International System of Units (SI). But the term “micron” is more commonly used in everyday usage.

The abbreviation for micrometer is μm. The single Unicode character ㎛ (U+339B) represents the 2-character Greek/Latin abbreviation for micrometer. The Windows Alt code for this character ㎛ is Alt + 13211.

## What is an inch (in)?

Definition of inch: An inch is an imperial and US customary unit of length equal to 1/12 of a foot or 2.54 centimeters. It is often used in the United States and the United Kingdom, that follow these measurement systems for small measurements such as in construction and carpentry.

The abbreviation for inch is in. The single Unicode character ㏌ (U+33CC) represents the 2-character Latin abbreviation for inch. The Windows Alt code for this character ㏌ is Alt + 13260.

The informal symbol for inch is represented by a double prime (″) or double quote (“). For example, 12 inches can be written as 12″.
