About Converting Nanometers to Picometers
Nanometer and Picometer both measure length. Specifically: Nanometer is 1e-9 meter units, and picometer is 1e-12 meter units.
Formula
picometers = nanometers × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanometer equals 1e-9 base units, and 1 picometer equals 1e-12 base units, so dividing one by the other gives the direct nanometer-to-picometer factor of 1000.
Simple example
1 nm × 1000 = 1,000 pm
1 nanometer = 1,000 picometers.
Real-world example
10 nm × 1000 = 10,000 pm
10 nanometers = 10,000 picometers.
Conversion table
| Nanometer (nm) | Picometer (pm) |

Reverse conversion: Picometer to Nanometer
1 pm × 0.001 = 0.001 nm
1 picometer = 0.001 nanometers.
nanometers = picometers × 0.001

Frequently asked questions
How many picometers are in 1 nanometer?
1 nanometer equals 1,000 picometers, using the exact defined conversion factor rather than an estimate.
How do I convert nanometer to picometer?
Multiply the nanometer value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert picometer back to nanometer?
Use the reverse factor: 1 picometer equals 0.001 nanometers. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanometer?
Nanometer (nm) is a unit of length.
What is a picometer?
Picometer (pm) is a unit of length.
Is the nanometer to picometer conversion exact?
Yes. Both nanometer and picometer are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
