How to Convert Feet to Micrometers

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

To convert a foot measurement to a micrometer measurement, multiply the length by the conversion ratio. One foot is equal to 304,800 micrometers, so use this simple formula to convert:

micrometers = feet × 304,800

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

For example, here's how to convert 5 feet to micrometers using the formula above.
5' = (5 × 304,800) = 1,524,000 µm

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

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


The foot is a unit of linear length measure 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.

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

The foot is most commonly measured 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 is simply the value of a length in feet, learn more.

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 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.

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.
