Convert bar to femtopascal
Please provide values below to convert bar [bar] to femtopascal [fPa], or Convert femtopascal to bar.
1 bar = 1.0000e+20 fPa. To convert bar to femtopascal, multiply the value by 1.0000e+20; to go the other way, divide by it (1 fPa = 1.0000e-20 bar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 bar = 1.0000e+20 fPa
- 1 fPa = 1.0000e-20 bar
- 10 bar = 1.0000e+21 fPa
- 100 bar = 1.0000e+22 fPa
How to Convert Bar to Femtopascal
1 bar = 1e+20 fPa
Example: convert 15 bar to fPa:
15 bar = 15 × 1e+20 fPa = 1.5e+21 fPa

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.
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.
Frequently Asked Questions
What is 1 bar in femtopascal?
1 bar (bar) = 1.0000e+20 femtopascal (fPa).
How do you convert bar to femtopascal?
Multiply the bar value by 1.0000e+20. For example, 25 bar × 1.0000e+20 = 2.5000e+21 fPa.
What is 10 bar in femtopascal?
10 bar = 1.0000e+21 fPa.
Which unit is larger, the bar or the femtopascal?
The bar is the larger unit: 1 bar = 1.0000e+20 fPa.
