About Converting Meter of waters to Kilopascals
Meter of water and Kilopascal 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 kilopascal is 1000 pascal units.
Formula
kilopascals = meter of waters × 9.80665
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 kilopascal equals 1000 base units, so dividing one by the other gives the direct meter of water-to-kilopascal factor of 9.80665.
Simple example
1 mH2O × 9.80665 = 9.80665 kPa
1 meter of water = 9.80665 kilopascals.
Real-world example
35 mH2O × 9.80665 = 343.23275 kPa
35 meter of waters = 343.23275 kilopascals.
