About Converting Square Gigameters to Sections
Comparing Square Gigameter and Section is common in agriculture and real estate, where US land is typically measured in acres and most of the rest of the world uses hectares. Specifically: Square metric area unit, and a US public land survey section is one square mile or 640 acres.
Formula
sections = square gigameters × 386102158542
This factor comes from each unit's defined relationship to the category's base unit: 1 square gigameter equals 1e+18 base units, and 1 section equals 2589988.11034 base units, so dividing one by the other gives the direct square gigameter-to-section factor of 386102158542.
Simple example
1 Gm2 × 386102158500 = 386,102,158,500 section
1 square gigameter = 386,102,158,500 sections.
Real-world example
10 Gm2 × 386102158500 = 3.861022e+12 section
10 square gigameters = 3.861022e+12 sections.
