About Converting Nanopascals to Megapascals

Nanopascal and Megapascal 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: Nanopascal is 1e-9 pascal units, and megapascal is 1000000 pascal units.

Formula

megapascals = nanopascals × 1e-15

This factor comes from each unit's defined relationship to the category's base unit: 1 nanopascal equals 1e-9 base units, and 1 megapascal equals 1000000 base units, so dividing one by the other gives the direct nanopascal-to-megapascal factor of 1e-15.

Simple example

1 nPa × 1e-15 = 1e-15 MPa

1 nanopascal = 1e-15 megapascals.

Real-world example

35 nPa × 1e-15 = 3.5e-14 MPa

35 nanopascals = 3.5e-14 megapascals.

Reverse conversion: Megapascal to Nanopascal

1e-15 MPa × 1e+15 = 1 nPa

1e-15 megapascals = 1 nanopascal.

nanopascals = megapascals × 1e+15

Frequently asked questions

How many megapascals are in 1 nanopascal?

1 nanopascal equals 1e-15 megapascals, using the exact defined conversion factor rather than an estimate.

How do I convert nanopascal to megapascal?

Multiply the nanopascal value by 1e-15. The converter above does this instantly to whatever precision you set.

How do I convert megapascal back to nanopascal?

Use the reverse factor: 1 megapascal equals 1e+15 nanopascals. You can also use the swap control in the converter above to flip the direction instantly.

What is a nanopascal?

Nanopascal (nPa) is a unit of pressure.

What is a megapascal?

Megapascal (MPa) is a unit of pressure.

Is the nanopascal to megapascal conversion exact?

Yes. Both nanopascal and megapascal are defined by fixed standards rather than physical artifacts, so the factor of 1e-15 used above is exact to as many digits as you choose to display.
