- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the centimeter of water value by 2.539999898. This alternative method also gives you the correct pressure in inch of waters.
- Illustration of Division:
- inH2O = cmh2o ÷ 2.539999898
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.
