Context values
Some unit families need one extra value for a physically accurate result.
A millibar is 100 pascals.
Result = input x 1000 / 100.
Pressure uses the pascal as the base unit.

About Converting Kilopascals to Millibars
Kilopascal and Millibar both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Kilopascal is 1000 pascal units, and a millibar is 100 pascals.
Formula
millibars = kilopascals × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 kilopascal equals 1000 base units, and 1 millibar equals 100 base units, so dividing one by the other gives the direct kilopascal-to-millibar factor of 10.
Simple example
1 kPa × 10 = 10 mbar
1 kilopascal = 10 millibars.
Real-world example
35 kPa × 10 = 350 mbar
35 kilopascals = 350 millibars.

Reverse conversion: Millibar to Kilopascal
10 mbar × 0.1 = 1 kPa
10 millibars = 1 kilopascal.
kilopascals = millibars × 0.1

Frequently asked questions
How many millibars are in 1 kilopascal?
1 kilopascal equals 10 millibars, using the exact defined conversion factor rather than an estimate.
How do I convert kilopascal to millibar?
Multiply the kilopascal value by 10. The converter above does this instantly to whatever precision you set.
How do I convert millibar back to kilopascal?
Use the reverse factor: 1 millibar equals 0.1 kilopascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilopascal?
Kilopascal (kPa) is a unit of pressure.
What is a millibar?
Millibar (mbar) is a unit of pressure.
Is the kilopascal to millibar conversion exact?
Yes. Both kilopascal and millibar are defined by fixed standards rather than physical artifacts, so the factor of 10 used above is exact to as many digits as you choose to display.
