About Converting Meter of waters to Torrs
Meter of water and Torr 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 a torr is 1/760 standard atmosphere.
Formula
torrs = meter of waters × 73.5559240069
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 torr equals 133.322368421 base units, so dividing one by the other gives the direct meter of water-to-torr factor of 73.5559240069.
Simple example
1 mH2O × 73.55592401 = 73.55592401 Torr
1 meter of water = 73.55592401 torrs.
Real-world example
35 mH2O × 73.55592401 = 2,574.45734 Torr
35 meter of waters = 2,574.45734 torrs.
