Convert inch mercury (60°F) to centimeter water (4°C)
Please provide values below to convert inch mercury (60°F) [inHg] to centimeter water (4°C) [cmH2O], or Convert centimeter water (4°C) to inch mercury (60°F).
How to Convert Inch Mercury (60°f) to Centimeter Water (4°c)
1 inHg = 34.4352350204663 cmH2O
Example: convert 15 inHg to cmH2O:
15 inHg = 15 × 34.4352350204663 cmH2O = 516.528525306994 cmH2O

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.
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.
