bar to nanopascal
Convert bar (bar) to nanopascal (nPa). Use an editable pressure converter, conversion formula, and reference table.
1 bar = 1e+14 nPa
Conversion formula
One bar equals 1e+14 nanopascal. Multiply your value in bar by this factor to get nanopascal. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 bar:5 × 1e+14 = 5e+14 nPa

About these measurements
Pressure is force per unit of area.
The base reference used here is the pascal. One bar is 100,000 base units; one nanopascal is 1e-9 base units.
Important distinctions
Gauge and absolute pressures must not be mixed. This converts units without changing the reference pressure.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert bar to nPa?
Multiply the quantity in bar by 1e+14. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the nanopascal to bar converter.
