How to Convert Meters to Micrometers

To convert a measurement in meters to a measurement in micrometers, multiply the length by the following conversion ratio: 1,000,000 micrometers/meter.

Since one meter is equal to 1,000,000 micrometers, you can use this simple formula to convert:

micrometers = meters × 1,000,000

The length in micrometers is equal to the length in meters multiplied by 1,000,000.

For example, here's how to convert 5 meters to micrometers using the formula above.

micrometers = (5 m × 1,000,000) = 5,000,000 µm

How Many Micrometers Are in a Meter?

There are 1,000,000 micrometers in a meter, which is why we use this value in the formula above.

1 m = 1,000,000 µm

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

What Is a Meter?

According to the most recent 2019 definition, the meter is defined as the distance traveled by light in vacuum during a time interval with a duration of 1/299,792,458 of a second.[1] One meter is equal to 100 centimeters, 3.28084 feet, or 39.37 inches.

The meter, or metre, is the SI base unit for length in the metric system. Meters can be abbreviated as m; for example, 1 meter can be written as 1 m.

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.

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.
