How to Convert Micrometers to Inches

Tape measures can be used to measure units of length, and a calculator can be used to convert to another unit

Convert micrometers to inches with this simple formula:

inches = micrometers × 3.937E-5

Converting a micrometer length measurement to an inch measurement involves multiplying the length by the conversion ratio to find the result. One micrometer is equal to 3.937E-5 inches, so to convert simply multiply by 3.937E-5.

For example:
5 µm = (5 × 3.937E-5) = 0.000197"

Our inch fraction calculator can add micrometers and inches together and it also automatically converts the results to both imperial and metric values.

Micrometers and inches are both units used to measure length. Learn more about length and find more length measurement conversion calculators. Micrometers are a metric measurement and can be abbreviated as µm, for example 1 µm. Inches are an imperial measurement and can be abbreviated as in, for example 1 in. Learn more about the metric system, including the common unit prefixes and how to convert between metric units.

A human hair is 40-50 micrometers thick or 0.000001 meters, making this a very small unit of measure. The micrometer is often referred to as a micron and internationally it is spelled micrometre.

The actual length of an inch has varied because of variances of the length of a foot. Throughout history it has been equal to 1/12 - 1/16 of a foot, but there are now exactly 12 inches in a foot. In 1959 the world agreed to the exact length of the national yard, .9144 meters. As such a foot is equal to .3048 meters and an inch is equal to 2.54 centimeters.

A quarter is .955" in diameter, which is just smaller than 1"

The standard ruler has 12", and metric combinations have 30 cm. Inches are also often measured using tape measures which commonly come in lengths from 6' - 35'. Other types of measuring devices include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs. If you need a ruler you can also download and print our free printable rulers which include both imperial and metric measurements.
