About Converting Metric tons per Square foot to Grams per Square Kilometer
Metric ton per Square foot and Gram per Square Kilometer both measure a farming-related quantity — a land area or an application/yield rate per unit area — used to report crop yields, calculate how much fertilizer or seed a field needs, and plan irrigation. Both are mass application rate units.
Formula
grams per square kilometer = metric tons per square foot × 1.076391e+13
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per square foot equals 10763.9104167 base units, and 1 gram per square kilometer equals 1e-9 base units, so dividing one by the other gives the direct metric ton per square foot-to-gram per square kilometer factor of 1.076391e+13.
Simple example
1 t/ft2 × 1.076391e+13 = 1.076391e+13 g/km2
1 metric ton per square foot = 1.076391e+13 grams per square kilometer.
Real-world example
100 t/ft2 × 1.076391e+13 = 1.076391e+15 g/km2
100 metric tons per square foot = 1.076391e+15 grams per square kilometer.
