Context values
Some unit families need one extra value for a physically accurate result.
Technical atmosphere is kilogram-force per square centimeter.
Result = input x 9806.65 / 98066.5.
Pressure uses the pascal as the base unit.

About Converting Meter of waters to Technical atmospheres
Meter of water and Technical atmosphere 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 technical atmosphere is kilogram-force per square centimeter.
Formula
technical atmospheres = meter of waters × 0.1
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 technical atmosphere equals 98066.5 base units, so dividing one by the other gives the direct meter of water-to-technical atmosphere factor of 0.1.
Simple example
1 mH2O × 0.1 = 0.1 at
1 meter of water = 0.1 technical atmospheres.
Real-world example
35 mH2O × 0.1 = 3.5 at
35 meter of waters = 3.5 technical atmospheres.
Conversion table
| Meter of water (mH2O) | Technical atmosphere (at) |
|---|---|
| 1 mH2O | 0.1 at |
| 5 mH2O | 0.5 at |
| 10 mH2O | 1 at |
| 25 mH2O | 2.5 at |
| 50 mH2O | 5 at |
| 100 mH2O | 10 at |
Reverse conversion: Technical atmosphere to Meter of water
0.1 at × 10 = 1 mH2O
0.1 technical atmospheres = 1 meter of water.
meter of waters = technical atmospheres × 10

Frequently asked questions
How many technical atmospheres are in 1 meter of water?
1 meter of water equals 0.1 technical atmospheres, using the exact defined conversion factor rather than an estimate.
How do I convert meter of water to technical atmosphere?
Multiply the meter of water value by 0.1. The converter above does this instantly to whatever precision you set.
How do I convert technical atmosphere back to meter of water?
Use the reverse factor: 1 technical atmosphere equals 10 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 pressure.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of pressure.
Is the meter of water to technical atmosphere conversion exact?
Yes. Both meter of water and technical atmosphere are defined by fixed standards rather than physical artifacts, so the factor of 0.1 used above is exact to as many digits as you choose to display.
