Convert Kilometers to Nanometers
1 kilometer = 1,000,000,000,000 nanometers. Type any value below to convert in either direction — the calculation happens in your browser.
Kilometers to Nanometers formula
Multiply the number of kilometers by 1000000000000 to get nanometers.
nanometers = kilometers × 1000000000000To go the other way: divide the number of nanometers by 1000000000000, or multiply by 1.000000e-12.
kilometers = nanometers ÷ 1000000000000Kilometers to Nanometers conversion table
