Convert Micrometers to Centimeters
1 micrometer is 0.0001 cm. One micrometer is exactly 0.0001 centimeters.
One micrometer is 1.0000 × 10^-4 centimeters. To convert micrometers to centimeters, multiply by 1.0000 × 10^-4; to go the other way, divide by 1.0000 × 10^-4 or multiply by 10000. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST. A millionth of a meter, still widely called a micron.

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: micrometres to centimetres 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 micrometers to centimeters? The converter and the working
- 1.Take the measurement in micrometers.
- 2.Multiply by 1.0000 × 10^-4 — that is how many centimeters fit in one micrometer.
- 3.To go back the other way, divide by 1.0000 × 10^-4, or multiply by 10000.
Worked example: 25 micrometers to centimeters
- Formula
- µm × 1.0000 × 10^-4 = cm
- Arithmetic
- 25 × 1.0000 × 10^-4 = 0.0025 cm
- Answer
- 25 µm = 0.0025 cm
The factor is rounded for display; the figure above is computed from the full value.

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.
What is a centimeter?
One hundredth of a meter, and the unit most of the world states height in.
How many centimeters are in a micrometer?
One micrometer is 1.0000 × 10^-4 centimeters. Going the other way, one centimeter is 10000 micrometers. 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.

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 micrometer.
