How to Convert at to mmH2O?
Converting from at to mmH2O is a straightforward process. Follow these steps to ensure accurate conversions from technical atmosphere to millimeter of water:
- Select the Technical Atmosphere Value: Start by determining the technical atmosphere (at) value you want to convert into millimeter of water (mmH2O). This is your starting point.
- Multiply by the Conversion Factor: To calculate technical atmosphere to equivalent millimeter of water amount, multiply the selected at value by 10000.
- Illustration of Multiplication:
- 1 at = 10000 mmH2O
- 10 at = 100000 mmH2O
- 100 at = 1000000 mmH2O
- Find the Conversion Result: The result of this multiplication is your converted value in millimeter of water unit. This represents the same pressure but in a different unit.
- Save Your Millimeter of Water Value: After converting, remember to save the result. This value represents the pressure you initially measured, now expressed in millimeter of waters.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the technical atmosphere value by 0.00010000000000000017. This alternative method also gives you the correct pressure in millimeter of waters.
- Illustration of Division:
- mmH2O = at ÷ 0.00010000000000000017
What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Technical Atmosphere?
Technical atmosphere (symbol: at) is a unit of pressure defined as the pressure exerted by one kilogram-force per square centimeter. One technical atmosphere is exactly equal to 98,066.5 pascals, 0.980665 bar, or 0.967841 standard atmosphere (atm). The technical atmosphere was widely used in engineering, hydraulics, and industrial pressure measurements, particularly in Europe, before SI units became the international standard. It is still encountered in older engineering documents and is commonly converted to pascals, bar, and standard atmospheres when interpreting historical specifications and technical data.

Technical Atmosphere to Millimeter of Water Examples
Example 1:
Convert 0.9 Technical Atmosphere pressure to Millimeter of Water unit.
Solution:
We know that one Technical Atmosphere is equivalent to 10000 Millimeter of Water.
Therefore,
0.9 at = 0.9 x 10000 mmH2O.
0.9 at = 9000 mmH2O.
Hence, 0.9 Technical Atmosphere is approximately equal to 9000 Millimeter of Water.
Example 2:
Convert 10 Technical Atmosphere pressure to Millimeter of Water unit.
Solution:
We know that one Technical Atmosphere is equivalent to 10000 Millimeter of Water.
Therefore,
10 at = 10 x 10000 mmH2O.
10 at = 100000 mmH2O.
Hence, 10 Technical Atmosphere is approximately equal to 100000 Millimeter of Water.
