Convert centimeter water (4°C) to inch mercury (60°F)
Please provide values below to convert centimeter water (4°C) [cmH2O] to inch mercury (60°F) [inHg], or Convert inch mercury (60°F) to centimeter water (4°C).
How to Convert Centimeter Water (4°c) to Inch Mercury (60°f)
1 cmH2O = 0.0290400225061818 inHg
Example: convert 15 cmH2O to inHg:
15 cmH2O = 15 × 0.0290400225061818 inHg = 0.435600337592727 inHg

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.
Inch Mercury (60°f)
Inch of mercury (60°F) is a unit of pressure measurement representing the height of a column of mercury 1 inch high at 60°F under standard gravity.
History/Origin
Originally used in barometry and meteorology, the inch of mercury has been a standard unit for measuring atmospheric pressure in the Imperial system since the 19th century.
Current Use
It is still used in some regions, such as the United States, primarily for measuring atmospheric pressure in weather reports and aviation, although it is gradually being replaced by Pascals in scientific contexts.
