## How the conversion works

The relationship is kPa = mbar × 1/10. Both units measure pressure, so the conversion is a fixed factor that never changes.

## Common questions

### How many kilopascals are in one millibar?

One millibar equals 0.1 kilopascals. kPa = mbar × 1/10.

### How do you convert millibars to kilopascals?

Use kPa = mbar × 1/10. So 10 mbar is 1 kPa.

### How many millibars are in one kilopascal?

One kilopascal equals 10 millibars, which is the reverse of the conversion above.
