About Converting Terapascals to Gigapascals
Terapascal 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: Terapascal is 1000000000000 pascal units, and gigapascal is 1000000000 pascal units.
Formula
gigapascals = terapascals × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 terapascal equals 1e+12 base units, and 1 gigapascal equals 1000000000 base units, so dividing one by the other gives the direct terapascal-to-gigapascal factor of 1000.
Simple example
1 TPa × 1000 = 1,000 GPa
1 terapascal = 1,000 gigapascals.
Real-world example
35 TPa × 1000 = 35,000 GPa
35 terapascals = 35,000 gigapascals.
