About Converting Decapascals to Gigapascals
Decapascal and Gigapascal 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 gigapascal is 1000000000 pascal units.
Formula
gigapascals = decapascals × 1e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 decapascal equals 10 base units, and 1 gigapascal equals 1000000000 base units, so dividing one by the other gives the direct decapascal-to-gigapascal factor of 1e-8.
Simple example
1 daPa × 1e-8 = 1e-8 GPa
1 decapascal = 1e-8 gigapascals.
Real-world example
35 daPa × 1e-8 = 3.5e-7 GPa
35 decapascals = 3.5e-7 gigapascals.

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