About Converting Sections to Square Megameters
Comparing Section and Square Megameter 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: A US public land survey section is one square mile or 640 acres, and square metric area unit.
Formula
square megameters = sections × 0.00000258998811034
This factor comes from each unit's defined relationship to the category's base unit: 1 section equals 2589988.11034 base units, and 1 square megameter equals 1e+12 base units, so dividing one by the other gives the direct section-to-square megameter factor of 0.00000258998811034.
Simple example
1 section × 0.00000258998811 = 0.00000259 Mm2
1 section = 0.00000259 square megameters.
