Convert centimeter water (4°C) to pascal
Please provide values below to convert centimeter water (4°C) [cmH2O] to pascal [Pa], or Convert pascal to centimeter water (4°C).
1 cmH2O = 98.0638 Pa. To convert centimeter water (4°C) to pascal, multiply the value by 98.0638; to go the other way, divide by it (1 Pa = 0.0101974428892 cmH2O). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 cmH2O = 98.0638 Pa
- 1 Pa = 0.0101974428892 cmH2O
- 10 cmH2O = 980.638 Pa

Centimeter Water (4°c)
Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.
History/Origin
The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.
Current Use
It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
History/Origin
Named after Blaise Pascal, the pascal was adopted as the SI unit of pressure in 1971, replacing earlier units like the bar and atmosphere.
Current Use
The pascal is widely used in science, engineering, and meteorology to measure pressure, with common applications including atmospheric pressure, tire pressure, and fluid pressure in systems.
