Please provide values below to convert femtopascal [fPa] to bar [bar], or Convert bar to femtopascal.
How to Convert Femtopascal to Bar
1 fPa = 1e-20 bar
Example: convert 15 fPa to bar:
15 fPa = 15 × 1e-20 bar = 1.5e-19 bar

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.
Bar
The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.
History/Origin
The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.
Current Use
The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
