About Converting Femtopascals to Nanopascals
Femtopascal and Nanopascal both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Femtopascal is 1e-15 pascal units, and nanopascal is 1e-9 pascal units.
Formula
nanopascals = femtopascals × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 femtopascal equals 1e-15 base units, and 1 nanopascal equals 1e-9 base units, so dividing one by the other gives the direct femtopascal-to-nanopascal factor of 0.000001.
Simple example
1 fPa × 0.000001 = 0.000001 nPa
1 femtopascal = 0.000001 nanopascals.
Real-world example
35 fPa × 0.000001 = 0.000035 nPa
35 femtopascals = 0.000035 nanopascals.

Reverse conversion: Nanopascal to Femtopascal
0.000001 nPa × 1000000 = 1 fPa
0.000001 nanopascals = 1 femtopascal.
femtopascals = nanopascals × 1000000

Frequently asked questions
How many nanopascals are in 1 femtopascal?
1 femtopascal equals 0.000001 nanopascals, using the exact defined conversion factor rather than an estimate.
How do I convert femtopascal to nanopascal?
Multiply the femtopascal value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert nanopascal back to femtopascal?
Use the reverse factor: 1 nanopascal equals 1,000,000 femtopascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a femtopascal?
Femtopascal (fPa) is a unit of pressure.
What is a nanopascal?
Nanopascal (nPa) is a unit of pressure.
Is the femtopascal to nanopascal conversion exact?
Yes. Both femtopascal and nanopascal are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
