Convert Meters to Micrometers

1 meter is 1,000,000 µm. One meter is exactly 1000000 micrometers.

One meter is 1000000 micrometers. To convert meters to micrometers, multiply by 1000000; to go the other way, divide by 1000000 or multiply by 1.0000 × 10^-6. The factor is exact rather than rounded: it follows from NIST. The SI base unit, defined since 1983 by the distance light travels in 1/299,792,458 of a second.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.

The same converter answers this pair however it is written: metres to micrometres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.

How do you convert meters to micrometers? The converter and the working

  1. 1.Take the measurement in meters.
  2. 2.Multiply by 1000000 — that is how many micrometers fit in one meter.
  3. 3.To go back the other way, divide by 1000000, or multiply by 1.0000 × 10^-6.

Worked example: 25 meters to micrometers

Formula
m × 1000000 = µm
Arithmetic
25 × 1000000 = 25,000,000 µm
Answer
25 m = 25,000,000 µm

The factor is exact, so this figure is exact too — only the display is rounded.

What is a meter?

The SI base unit, defined since 1983 by the distance light travels in 1/299,792,458 of a second.

What is a micrometer?

A millionth of a meter, still widely called a micron. Machining tolerances, filter ratings and cell diameters are all quoted here.

How many micrometers are in a meter?

One meter is 1000000 micrometers, exactly. Going the other way, one micrometer is 1.0000 × 10^-6 meters. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

Every length unit here

The whole group — 13 units with their symbols and the size of each one in meters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a meter.
