About Converting Decapascals to Hectopascals
Decapascal and Hectopascal 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: Decapascal is 10 pascal units, and hectopascal is 100 pascal units.
Formula
hectopascals = decapascals × 0.1
This factor comes from each unit's defined relationship to the category's base unit: 1 decapascal equals 10 base units, and 1 hectopascal equals 100 base units, so dividing one by the other gives the direct decapascal-to-hectopascal factor of 0.1.
Simple example
1 daPa × 0.1 = 0.1 hPa
1 decapascal = 0.1 hectopascals.
Real-world example
35 daPa × 0.1 = 3.5 hPa
35 decapascals = 3.5 hectopascals.
Conversion table

Reverse conversion: Hectopascal to Decapascal
0.1 hPa × 10 = 1 daPa
0.1 hectopascals = 1 decapascal.
decapascals = hectopascals × 10

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