About Converting Meter of waters to Terapascals
Meter of water and Terapascal 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: Meter of water column, and terapascal is 1000000000000 pascal units.
Formula
terapascals = meter of waters × 9.80665e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 meter of water equals 9806.65 base units, and 1 terapascal equals 1e+12 base units, so dividing one by the other gives the direct meter of water-to-terapascal factor of 9.80665e-9.
Simple example
1 mH2O × 9.80665e-9 = 9.80665e-9 TPa
1 meter of water = 9.80665e-9 terapascals.
Real-world example
35 mH2O × 9.80665e-9 = 3.432328e-7 TPa
35 meter of waters = 3.432328e-7 terapascals.
