# Centimeters to micrometers

**1 centimeter in micrometers: 1 cm = 10,000 µm**

µm = cm × 10,000

To convert centimeters to micrometers, multiply by 10,000. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is µm = cm × 10,000. Both units measure length, so the conversion is a fixed factor that never changes.

## Common questions

### How many micrometers are in one centimeter?

One centimeter equals 10,000 micrometers. µm = cm × 10,000.

### How do you convert centimeters to micrometers?

Use µm = cm × 10,000. So 10 cm is 100,000 µm.

### How many centimeters are in one micrometer?

One micrometer equals 0.0001 centimeters, which is the reverse of the conversion above.
