Formula
rontograms = gigagrams × 1e+36
This factor comes from each unit's defined relationship to the category's base unit: 1 gigagram equals 1000000 base units, and 1 rontogram equals 1e-30 base units, so dividing one by the other gives the direct gigagram-to-rontogram factor of 1e+36.
Simple example
1 Gg × 1e+36 = 1e+36 rg
1 gigagram = 1e+36 rontograms.
Real-world example
50 Gg × 1e+36 = 5e+37 rg
50 gigagrams = 5e+37 rontograms.
