Convert millimeter water (4°C) to megapascal
Please provide values below to convert millimeter water (4°C) [mmH2O] to megapascal [MPa], or Convert megapascal to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Megapascal
1 mmH2O = 9.80638e-06 MPa
Example: convert 15 mmH2O to MPa:
15 mmH2O = 15 × 9.80638e-06 MPa = 0.0001470957 MPa

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.
Megapascal
The megapascal (MPa) is a unit of pressure equal to one million pascals, where one pascal (Pa) is the pressure exerted by a force of one newton per square meter.
History/Origin
The megapascal was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring high pressures, especially in engineering and scientific applications, replacing larger units like the bar in many contexts.
Current Use
The MPa is widely used today in engineering, material science, and industrial applications to specify pressures in fields such as hydraulics, pneumatics, and structural engineering.
