About Converting Gigameters to Decameters
Gigameter and Decameter both measure length. Specifically: Gigameter is 1000000000 meter units, and decameter is 10 meter units.
Formula
decameters = gigameters × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 gigameter equals 1000000000 base units, and 1 decameter equals 10 base units, so dividing one by the other gives the direct gigameter-to-decameter factor of 100000000.
Simple example
1 Gm × 100000000 = 100,000,000 dam
1 gigameter = 100,000,000 decameters.
Real-world example
10 Gm × 100000000 = 1,000,000,000 dam
10 gigameters = 1,000,000,000 decameters.
