About Converting Gigapascals to Petapascals
Gigapascal and Petapascal 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 petapascal is 1000000000000000 pascal units.
Formula
petapascals = gigapascals × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 gigapascal equals 1000000000 base units, and 1 petapascal equals 1e+15 base units, so dividing one by the other gives the direct gigapascal-to-petapascal factor of 0.000001.
Simple example
1 GPa × 0.000001 = 0.000001 PPa
1 gigapascal = 0.000001 petapascals.
Real-world example
35 GPa × 0.000001 = 0.000035 PPa
35 gigapascals = 0.000035 petapascals.

Reverse conversion: Petapascal to Gigapascal
0.000001 PPa × 1000000 = 1 GPa
0.000001 petapascals = 1 gigapascal.
gigapascals = petapascals × 1000000

Frequently asked questions
How many petapascals are in 1 gigapascal?
1 gigapascal equals 0.000001 petapascals, using the exact defined conversion factor rather than an estimate.
How do I convert gigapascal to petapascal?
Multiply the gigapascal value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert petapascal back to gigapascal?
Use the reverse factor: 1 petapascal equals 1,000,000 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 petapascal?
Petapascal (PPa) is a unit of pressure.
Is the gigapascal to petapascal conversion exact?
Yes. Both gigapascal and petapascal are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
