About Converting Meter of waters to Torrs
Meter of water and Torr 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: 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
100 mH2O × 73.55592401 = 7,355.592401 Torr
100 meter of waters = 7,355.592401 torrs.

Frequently asked questions
How many torrs are in 1 meter of water?
1 meter of water equals 73.55592401 torrs, using the exact defined conversion factor rather than an estimate.
How do I convert meter of water to torr?
Multiply the meter of water value by 73.55592401. The converter above does this instantly to whatever precision you set.
How do I convert torr back to meter of water?
Use the reverse factor: 1 torr equals 0.0135950981 meter of waters. You can also use the swap control in the converter above to flip the direction instantly.
What is a meter of water?
Meter of water (mH2O) is a unit of engineering.
What is a torr?
Torr (Torr) is a unit of engineering.
Is the meter of water to torr conversion exact?
Yes. Both meter of water and torr are defined by fixed standards rather than physical artifacts, so the factor of 73.55592401 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.
