Formula
metric tons per acre = milligrams per square foot × 0.00004356
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per square foot equals 0.0000107639104167 base units, and 1 metric ton per acre equals 0.247105381467 base units, so dividing one by the other gives the direct milligram per square foot-to-metric ton per acre factor of 0.00004356.
Simple example
1 mg/ft2 × 0.00004356 = 0.00004356 t/ac
1 milligram per square foot = 0.00004356 metric tons per acre.
Real-world example
100 mg/ft2 × 0.00004356 = 0.004356 t/ac
100 milligrams per square foot = 0.004356 metric tons per acre.
