Kilometers to Nanometers: 1 km equals 1.00000e+12 nm. To convert kilometers to nanometers, multiply by 1.00000e+12 (nm = km × 1,000,000,000,000). For example, 10 km = 1.00000e+13 nm.
How to Convert Kilometers to Nanometers
To convert from kilometers to nanometers, multiply the value by 1.00000e+12. The conversion is linear, meaning doubling the input doubles the output.
Conversion Formula
- Kilometers to Nanometers:
nm = km × 1,000,000,000,000 - Nanometers to Kilometers:
km = nm ÷ 1,000,000,000,000
