How to Convert Micrometers to Feet

To convert a measurement in micrometers to a measurement in feet, divide the length by the following conversion ratio: 304,800 micrometers/foot.

Since one foot is equal to 304,800 micrometers, you can use this simple formula to convert:

feet = micrometers ÷ 304,800

The length in feet is equal to the length in micrometers divided by 304,800.

For example, here's how to convert 500,000 micrometers to feet using the formula above.
feet = (500,000 µm ÷ 304,800) = 1.64042'

Our inch fraction calculator can add micrometers and feet together, and it also automatically converts the results to US customary, imperial, and SI metric values.

Micrometers and feet are both units used to measure length. Keep reading to learn more about each unit of measure.

What Is a Micrometer?

One micrometer is equal to one-millionth (1/1,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The micrometer, or micrometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "micro" is the prefix for millionths, or 10-6. A micrometer is sometimes also referred to as a micron. Micrometers can be abbreviated as µm; for example, 1 micrometer can be written as 1 µm.

To get an idea of the actual physical length of a micrometer, one human hair is 40-50 µm thick, demonstrating how small this unit of measure is.

What Is a Foot?

The foot is a unit of length measurement equal to 12 inches or 1/3 of a yard. Because the international yard is legally defined to be equal to exactly 0.9144 meters, one foot is equal to 0.3048 meters.[1]

The foot is a US customary and imperial unit of length. Feet can be abbreviated as ft; for example, 1 foot can be written as 1 ft.

Feet can also be denoted using the symbol, otherwise known as a prime, though a single-quote (') is often used instead of the prime symbol for convenience. Using the prime symbol, 1 ft can be written as 1′.

Measurements in feet are most commonly taken using either a standard 12" ruler or a tape measure, though there are many other measuring devices available. Feet are sometimes referred to as linear feet, which are simply a measurement of length in feet.

You might be interested in our feet and inches calculator, which can add feet with other units of measurement such as inches, centimeters, or meters.

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 a combination of both values, so make sure you get the correct type for your needs.
