About Converting Meter of waters to Decapascals
Meter of water and Decapascal 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 decapascal is 10 pascal units.
Formula
decapascals = meter of waters × 980.665
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 decapascal equals 10 base units, so dividing one by the other gives the direct meter of water-to-decapascal factor of 980.665.
Simple example
1 mH2O × 980.665 = 980.665 daPa
1 meter of water = 980.665 decapascals.
Real-world example
35 mH2O × 980.665 = 34,323.275 daPa
35 meter of waters = 34,323.275 decapascals.
