About Converting Square Megameters to Sections
Comparing Square Megameter 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 megameters × 386102.158542
This factor comes from each unit's defined relationship to the category's base unit: 1 square megameter equals 1e+12 base units, and 1 section equals 2589988.11034 base units, so dividing one by the other gives the direct square megameter-to-section factor of 386102.158542.
Simple example
1 Mm2 × 386102.1585 = 386,102.1585 section
1 square megameter = 386,102.1585 sections.
