About Converting Meter of waters to Yottapascals
Meter of water and Yottapascal 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 yottapascal is 1e+24 pascal units.
Formula
yottapascals = meter of waters × 9.80665e-21
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 yottapascal equals 1e+24 base units, so dividing one by the other gives the direct meter of water-to-yottapascal factor of 9.80665e-21.
Simple example
1 mH2O × 9.80665e-21 = 9.80665e-21 YPa
1 meter of water = 9.80665e-21 yottapascals.
Real-world example
35 mH2O × 9.80665e-21 = 3.432328e-19 YPa
35 meter of waters = 3.432328e-19 yottapascals.
