cm to Micrometers Converter (cm to µm)

How to convert centimeters to micrometers

Formulaµm = cm × 10,000

Multiply the value in centimeters by 10,000. To go the other way, multiply by 0.0001 (or divide by 10,000).

A centimeter is larger than a micrometer: one centimeter contains 10,000 micrometers.

About the units

Centimeter (cm)

One hundredth of a metre. Centimetres are the everyday metric unit for body height, clothing sizes and small objects; a standard paper clip is about 3 cm long. One centimeter equals 0.01 meters (m).

Micrometer (µm)

One millionth of a metre, often called a micron. Human hair is roughly 50–100 µm across, and filter and particle sizes are given in micrometres. One micrometer equals 0.000001 meters (m).

Frequently asked questions

How many micrometers are in one centimeter?

There are 10,000 micrometers in one centimeter, and this value is exact by definition.

How do I convert centimeters to micrometers?

Multiply the number of centimeters by 10,000. For example, 10 cm × 10,000 = 100,000 µm.

How many centimeters are in one micrometer?

One micrometer equals 0.0001 centimeters. That is the reverse factor, 1 ÷ 10,000.

What is 10 centimeters in micrometers?

10 cm = 100,000 µm.

Is this cm to µm converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
