About Converting Gigapascals to Decapascals
Gigapascal 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: Gigapascal is 1000000000 pascal units, and decapascal is 10 pascal units.
Formula
decapascals = gigapascals × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 gigapascal equals 1000000000 base units, and 1 decapascal equals 10 base units, so dividing one by the other gives the direct gigapascal-to-decapascal factor of 100000000.
Simple example
1 GPa × 100000000 = 100,000,000 daPa
1 gigapascal = 100,000,000 decapascals.
Real-world example
35 GPa × 100000000 = 3,500,000,000 daPa
35 gigapascals = 3,500,000,000 decapascals.

Frequently asked questions
How many decapascals are in 1 gigapascal?
1 gigapascal equals 100,000,000 decapascals, using the exact defined conversion factor rather than an estimate.
How do I convert gigapascal to decapascal?
Multiply the gigapascal value by 100000000. The converter above does this instantly to whatever precision you set.
How do I convert decapascal back to gigapascal?
Use the reverse factor: 1 decapascal equals 1e-8 gigapascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigapascal?
Gigapascal (GPa) is a unit of pressure.
What is a decapascal?
Decapascal (daPa) is a unit of pressure.
Is the gigapascal to decapascal conversion exact?
Yes. Both gigapascal and decapascal are defined by fixed standards rather than physical artifacts, so the factor of 100000000 used above is exact to as many digits as you choose to display.
