Convert millimeter mercury (0°C) to femtopascal
Please provide values below to convert millimeter mercury (0°C) [mmHg] to femtopascal [fPa], or Convert femtopascal to millimeter mercury (0°C).
How to Convert Millimeter Mercury (0°c) to Femtopascal
1 mmHg = 1.33322387e+17 fPa
Example: convert 15 mmHg to fPa:
15 mmHg = 15 × 1.33322387e+17 fPa = 1.999835805e+18 fPa

Millimeter Mercury (0°c)
Millimeter mercury (0°C), abbreviated as mmHg, is a unit of pressure measurement based on the height of a column of mercury in millimeters at 0°C under standard gravity.
History/Origin
The mmHg originated from the use of mercury barometers in the 17th century to measure atmospheric pressure. It became a standard unit in meteorology and medicine for measuring blood pressure and other pressure-related phenomena.
Current Use
Today, mmHg is primarily used in medicine to measure blood pressure and in meteorology for atmospheric pressure readings. It is also used in various scientific and industrial applications where precise pressure measurements are required.
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.
