About Converting Gigameters to Petameters
Gigameter and Petameter both measure length. Specifically: Gigameter is 1000000000 meter units, and petameter is 1000000000000000 meter units.
Formula
petameters = gigameters × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 gigameter equals 1000000000 base units, and 1 petameter equals 1e+15 base units, so dividing one by the other gives the direct gigameter-to-petameter factor of 0.000001.
Simple example
1 Gm × 0.000001 = 0.000001 Pm
1 gigameter = 0.000001 petameters.
Real-world example
10 Gm × 0.000001 = 0.00001 Pm
10 gigameters = 0.00001 petameters.
