About Converting Nanometers to Decimeters
Nanometer and Decimeter both measure length. Specifically: Nanometer is 1e-9 meter units, and decimeter is 0.1 meter units.
Formula
decimeters = nanometers × 1e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 nanometer equals 1e-9 base units, and 1 decimeter equals 0.1 base units, so dividing one by the other gives the direct nanometer-to-decimeter factor of 1e-8.
Simple example
1 nm × 1e-8 = 1e-8 dm
1 nanometer = 1e-8 decimeters.
Real-world example
10 nm × 1e-8 = 1e-7 dm
10 nanometers = 1e-7 decimeters.

Frequently asked questions
How many decimeters are in 1 nanometer?
1 nanometer equals 1e-8 decimeters, using the exact defined conversion factor rather than an estimate.
How do I convert nanometer to decimeter?
Multiply the nanometer value by 1e-8. The converter above does this instantly to whatever precision you set.
How do I convert decimeter back to nanometer?
Use the reverse factor: 1 decimeter equals 100,000,000 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 decimeter?
Decimeter (dm) is a unit of length.
Is the nanometer to decimeter conversion exact?
Yes. Both nanometer and decimeter are defined by fixed standards rather than physical artifacts, so the factor of 1e-8 used above is exact to as many digits as you choose to display.
