About Converting Decameters to Nanometers
Decameter and Nanometer both measure length. Specifically: Decameter is 10 meter units, and nanometer is 1e-9 meter units.
Formula
nanometers = decameters × 10000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 decameter equals 10 base units, and 1 nanometer equals 1e-9 base units, so dividing one by the other gives the direct decameter-to-nanometer factor of 10000000000.
Simple example
1 dam × 10000000000 = 10,000,000,000 nm
1 decameter = 10,000,000,000 nanometers.
Real-world example
10 dam × 10000000000 = 100,000,000,000 nm
10 decameters = 100,000,000,000 nanometers.

Frequently asked questions
How many nanometers are in 1 decameter?
1 decameter equals 10,000,000,000 nanometers, using the exact defined conversion factor rather than an estimate.
How do I convert decameter to nanometer?
Multiply the decameter value by 10000000000. The converter above does this instantly to whatever precision you set.
How do I convert nanometer back to decameter?
Use the reverse factor: 1 nanometer equals 1e-10 decameters. You can also use the swap control in the converter above to flip the direction instantly.
What is a decameter?
Decameter (dam) is a unit of length.
What is a nanometer?
Nanometer (nm) is a unit of length.
Is the decameter to nanometer conversion exact?
Yes. Both decameter and nanometer are defined by fixed standards rather than physical artifacts, so the factor of 10000000000 used above is exact to as many digits as you choose to display.
