Convert millimeter water (4°C) to bar
Please provide values below to convert millimeter water (4°C) [mmH2O] to bar [bar], or Convert bar to millimeter water (4°C).
1 mmH2O = 9.80638e-05 bar. To convert millimeter water (4°C) to bar, multiply the value by 9.80638e-05; to go the other way, divide by it (1 bar = 10197.4428892 mmH2O). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mmH2O = 9.80638e-05 bar
- 1 bar = 10197.4428892 mmH2O
- 10 mmH2O = 0.000980638 bar

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.
Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
Frequently Asked Questions
