Convert millimeter water (4°C) to femtopascal
Please provide values below to convert millimeter water (4°C) [mmH2O] to femtopascal [fPa], or Convert femtopascal to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Femtopascal
1 mmH2O = 9.80638e+15 fPa
Example: convert 15 mmH2O to fPa:
15 mmH2O = 15 × 9.80638e+15 fPa = 1.470957e+17 fPa

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.
Femtopascal
The femtopascal (fPa) is a unit of pressure equal to 10^-15 pascals.
History/Origin
The femtopascal is a derived SI unit introduced as part of the International System of Units' effort to create a comprehensive set of prefixes for very small measurements, although it is rarely used in practice.
Current Use
The femtopascal is primarily used in scientific research involving extremely low pressure measurements, such as in nanotechnology and quantum physics, but it remains a theoretical unit with limited practical application.
