Micrometers to cm Converter (µm to cm)

How to convert micrometers to centimeters

Formulacm = µm × 0.0001

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

A micrometer is smaller than a centimeter: it takes 10,000 micrometers to make one centimeter.

About the units

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).

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).

Frequently asked questions

How many centimeters are in one micrometer?

There are 0.0001 centimeters in one micrometer, and this value is exact by definition.

How do I convert micrometers to centimeters?

Multiply the number of micrometers by 0.0001. For example, 10 µm × 0.0001 = 0.001 cm.

How many micrometers are in one centimeter?

One centimeter equals 10,000 micrometers. That is the reverse factor, 1 ÷ 0.0001.

What is 10 micrometers in centimeters?

10 µm = 0.001 cm.

Is this µm to cm 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.
