About Converting Millibars to Decapascals
Millibar and Decapascal 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: A millibar is 100 pascals, and decapascal is 10 pascal units.
Formula
decapascals = millibars × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 millibar equals 100 base units, and 1 decapascal equals 10 base units, so dividing one by the other gives the direct millibar-to-decapascal factor of 10.
Simple example
1 mbar × 10 = 10 daPa
1 millibar = 10 decapascals.
Real-world example
35 mbar × 10 = 350 daPa
35 millibars = 350 decapascals.

Frequently asked questions
How many decapascals are in 1 millibar?
1 millibar equals 10 decapascals, using the exact defined conversion factor rather than an estimate.
How do I convert millibar to decapascal?
Multiply the millibar value by 10. The converter above does this instantly to whatever precision you set.
How do I convert decapascal back to millibar?
Use the reverse factor: 1 decapascal equals 0.1 millibars. You can also use the swap control in the converter above to flip the direction instantly.
What is a millibar?
Millibar (mbar) is a unit of pressure.
What is a decapascal?
Decapascal (daPa) is a unit of pressure.
Is the millibar to decapascal conversion exact?
Yes. Both millibar and decapascal 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.
