Please provide values below to convert millimeter water (4°C) [mmH2O] to terapascal [TPa], or Convert terapascal to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Terapascal
1 mmH2O = 9.80638e-12 TPa
Example: convert 15 mmH2O to TPa:
15 mmH2O = 15 × 9.80638e-12 TPa = 1.470957e-10 TPa

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.
Terapascal
A terapascal (TPa) is a unit of pressure equal to one trillion pascals (10^12 Pa).
History/Origin
The terapascal was introduced as part of the International System of Units (SI) to measure extremely high pressures, especially in scientific research involving materials under extreme conditions, such as in geophysics and high-energy physics.
Current Use
The terapascal is used in scientific fields to quantify very high pressures, such as in studying Earth's deep interior, material science, and high-pressure physics experiments.
