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.
Inch Water (4°c)
Inch water (4°C) is a unit of pressure measurement representing the pressure exerted by a one-inch column of water at 4 degrees Celsius.
History/Origin
The inch water (4°C) has been used historically in engineering and meteorology to measure low-pressure differences, especially in ventilation and HVAC systems, as a practical alternative to more complex units.
Current Use
Today, inch water (4°C) is primarily used in the United States for measuring low-pressure differences in HVAC, ventilation, and fluid systems, serving as a standard unit in these fields within the pressure converter category of common converters.
