Convert millimeter water (4°C) to gigapascal
Please provide values below to convert millimeter water (4°C) [mmH2O] to gigapascal [GPa], or Convert gigapascal to millimeter water (4°C).
1 mmH2O = 9.80638e-09 GPa. To convert millimeter water (4°C) to gigapascal, multiply the value by 9.80638e-09; to go the other way, divide by it (1 GPa = 101974428.892 mmH2O). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
Gigapascal
A gigapascal (GPa) is a unit of pressure equal to one billion pascals, where one pascal (Pa) is the force of one newton per square meter.
History/Origin
The gigapascal was introduced as part of the International System of Units (SI) to measure high-pressure phenomena, especially in materials science and geophysics, as a larger unit than the pascal for convenience.
Current Use
GPa is commonly used to quantify stress, pressure in geological formations, material strength, and high-pressure physics applications.
