About Converting Technical atmospheres to Decipascals
Technical atmosphere and Decipascal 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: Technical atmosphere is kilogram-force per square centimeter, and decipascal is 0.1 pascal units.
Formula
decipascals = technical atmospheres × 980665
This factor comes from each unit's defined relationship to the category's base unit: 1 technical atmosphere equals 98066.5 base units, and 1 decipascal equals 0.1 base units, so dividing one by the other gives the direct technical atmosphere-to-decipascal factor of 980665.
Simple example
1 at × 980665 = 980,665 dPa
1 technical atmosphere = 980,665 decipascals.
Real-world example
35 at × 980665 = 34,323,275 dPa
35 technical atmospheres = 34,323,275 decipascals.

Frequently asked questions
How many decipascals are in 1 technical atmosphere?
1 technical atmosphere equals 980,665 decipascals, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to decipascal?
Multiply the technical atmosphere value by 980665. The converter above does this instantly to whatever precision you set.
How do I convert decipascal back to technical atmosphere?
Use the reverse factor: 1 decipascal equals 0.0000010197 technical atmospheres. You can also use the swap control in the converter above to flip the direction instantly.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of pressure.
What is a decipascal?
Decipascal (dPa) is a unit of pressure.
Is the technical atmosphere to decipascal conversion exact?
Yes. Both technical atmosphere and decipascal are defined by fixed standards rather than physical artifacts, so the factor of 980665 used above is exact to as many digits as you choose to display.
