Convert bar to nanopascal
Please provide values below to convert bar [bar] to nanopascal [nPa], or Convert nanopascal to bar.
1 bar = 1.0000e+14 nPa. To convert bar to nanopascal, multiply the value by 1.0000e+14; to go the other way, divide by it (1 nPa = 1.0000e-14 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+14 nPa
- 1 nPa = 1.0000e-14 bar
- 10 bar = 1.0000e+15 nPa
- 100 bar = 1.0000e+16 nPa
How to Convert Bar to Nanopascal
1 bar = 100000000000000 nPa
Example: convert 15 bar to nPa:
15 bar = 15 × 100000000000000 nPa = 1.5e+15 nPa

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.
Nanopascal
The nanopascal (nPa) is a unit of pressure equal to one billionth of a pascal, where 1 nPa = 10^-9 Pa.
History/Origin
The nanopascal was introduced as part of the SI unit system's extension to accommodate very small pressure measurements, primarily in scientific research involving micro- and nanoscale phenomena.
Current Use
Nanopascals are used in high-precision scientific applications such as atmospheric pressure measurements, microfluidics, and nanotechnology research where extremely low pressure differences need to be quantified.
Frequently Asked Questions
What is 1 bar in nanopascal?
1 bar (bar) = 1.0000e+14 nanopascal (nPa).
How do you convert bar to nanopascal?
Multiply the bar value by 1.0000e+14. For example, 25 bar × 1.0000e+14 = 2.5000e+15 nPa.
What is 10 bar in nanopascal?
10 bar = 1.0000e+15 nPa.
Which unit is larger, the bar or the nanopascal?
The bar is the larger unit: 1 bar = 1.0000e+14 nPa.
