About Converting Picometers to Nanometers
Picometer and Nanometer both measure length. Specifically: Picometer is 1e-12 meter units, and nanometer is 1e-9 meter units.
Formula
nanometers = picometers × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 picometer equals 1e-12 base units, and 1 nanometer equals 1e-9 base units, so dividing one by the other gives the direct picometer-to-nanometer factor of 0.001.
Simple example
1 pm × 0.001 = 0.001 nm
1 picometer = 0.001 nanometers.
Real-world example
10 pm × 0.001 = 0.01 nm
10 picometers = 0.01 nanometers.

Frequently asked questions
How many nanometers are in 1 picometer?
1 picometer equals 0.001 nanometers, using the exact defined conversion factor rather than an estimate.
How do I convert picometer to nanometer?
Multiply the picometer value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert nanometer back to picometer?
Use the reverse factor: 1 nanometer equals 1,000 picometers. You can also use the swap control in the converter above to flip the direction instantly.
What is a picometer?
Picometer (pm) is a unit of length.
What is a nanometer?
Nanometer (nm) is a unit of length.
Is the picometer to nanometer conversion exact?
Yes. Both picometer and nanometer are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
