About Converting Torrs to Meter of waters
Torr and Meter of water both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: A torr is 1/760 standard atmosphere, and meter of water column.
Formula
meter of waters = torrs × 0.0135950980632
This factor comes from each unit's defined relationship to the category's base unit: 1 torr equals 133.322368421 base units, and 1 meter of water equals 9806.65 base units, so dividing one by the other gives the direct torr-to-meter of water factor of 0.0135950980632.
Simple example
1 Torr × 0.01359509806 = 0.0135950981 mH2O
1 torr = 0.0135950981 meter of waters.
Real-world example
100 Torr × 0.01359509806 = 1.359509806 mH2O
100 torrs = 1.359509806 meter of waters.

Frequently asked questions
How many meter of waters are in 1 torr?
1 torr equals 0.0135950981 meter of waters, using the exact defined conversion factor rather than an estimate.
How do I convert torr to meter of water?
Multiply the torr value by 0.01359509806. The converter above does this instantly to whatever precision you set.
How do I convert meter of water back to torr?
Use the reverse factor: 1 meter of water equals 73.55592401 torrs. You can also use the swap control in the converter above to flip the direction instantly.
What is a torr?
Torr (Torr) is a unit of engineering.
What is a meter of water?
Meter of water (mH2O) is a unit of engineering.
Is the torr to meter of water conversion exact?
Yes. Both torr and meter of water are defined by fixed standards rather than physical artifacts, so the factor of 0.01359509806 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
