Context values
Some unit families need one extra value for a physically accurate result.
A millibar is 100 pascals.
Result = input x 0.01 / 100.
Pressure uses the pascal as the base unit.

About Converting Centipascals to Millibars
Centipascal 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: Centipascal is 0.01 pascal units, and a millibar is 100 pascals.
Formula
millibars = centipascals × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 centipascal equals 0.01 base units, and 1 millibar equals 100 base units, so dividing one by the other gives the direct centipascal-to-millibar factor of 0.0001.
Simple example
1 cPa × 0.0001 = 0.0001 mbar
1 centipascal = 0.0001 millibars.
Real-world example
35 cPa × 0.0001 = 0.0035 mbar
35 centipascals = 0.0035 millibars.

Reverse conversion: Millibar to Centipascal
0.0001 mbar × 10000 = 1 cPa
0.0001 millibars = 1 centipascal.
centipascals = millibars × 10000

Frequently asked questions
How many millibars are in 1 centipascal?
1 centipascal equals 0.0001 millibars, using the exact defined conversion factor rather than an estimate.
How do I convert centipascal to millibar?
Multiply the centipascal value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert millibar back to centipascal?
Use the reverse factor: 1 millibar equals 10,000 centipascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a centipascal?
Centipascal (cPa) is a unit of pressure.
What is a millibar?
Millibar (mbar) is a unit of pressure.
Is the centipascal to millibar conversion exact?
Yes. Both centipascal and millibar are defined by fixed standards rather than physical artifacts, so the factor of 0.0001 used above is exact to as many digits as you choose to display.
