How to Convert Kilometers to Picometers
The kilometer and picometer are both units of length. By definition, 1 kilometer equals exactly 1e15 picometers. This means to convert kilometers to picometers, you multiply by 1e15.
Formula
Step-by-Step Example
Convert 5 km to picometers:
We need to convert kilometers to picometers
Since 1 km = 1e15 pm, multiply by 1e15
5 × 1e15 = 5e15
5 km = 5e15 pm
