About Converting Meter of waters to Megapascals
Meter of water and Megapascal 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 megapascal is 1000000 pascal units.
Formula
megapascals = meter of waters × 0.00980665
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 megapascal equals 1000000 base units, so dividing one by the other gives the direct meter of water-to-megapascal factor of 0.00980665.
Simple example
1 mH2O × 0.00980665 = 0.00980665 MPa
1 meter of water = 0.00980665 megapascals.
Real-world example
35 mH2O × 0.00980665 = 0.34323275 MPa
35 meter of waters = 0.34323275 megapascals.
