Convert inch mercury (60°F) to millimeter water (4°C)
Please provide values below to convert inch mercury (60°F) [inHg] to millimeter water (4°C) [mmH2O], or Convert millimeter water (4°C) to inch mercury (60°F).
How to Convert Inch Mercury (60°f) to Millimeter Water (4°c)
1 inHg = 344.352350204663 mmH2O
Example: convert 15 inHg to mmH2O:
15 inHg = 15 × 344.352350204663 mmH2O = 5165.28525306994 mmH2O

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.
Millimeter Water (4°c)
Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.
History/Origin
The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.
Current Use
It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.
