About Converting Grams per Square Meter to Metric tons per Square Meter
Gram per Square Meter and Metric ton per Square Meter 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
metric tons per square meter = grams per square meter × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per square meter equals 0.001 base units, and 1 metric ton per square meter equals 1000 base units, so dividing one by the other gives the direct gram per square meter-to-metric ton per square meter factor of 0.000001.
Simple example
1 g/m2 × 0.000001 = 0.000001 t/m2
1 gram per square meter = 0.000001 metric tons per square meter.
Real-world example
100 g/m2 × 0.000001 = 0.0001 t/m2
100 grams per square meter = 0.0001 metric tons per square meter.

What is a gram per square meter?
Gram per Square Meter (g/m2) is a unit of agriculture.
What is a metric ton per square meter?
Metric ton per Square Meter (t/m2) is a unit of agriculture.
Is the gram per square meter to metric ton per square meter conversion exact?
Yes. Both gram per square meter and metric ton per square meter are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
What's the difference between a yield rate and an application rate?
A yield rate describes how much of a crop is harvested per unit of land area (for example, tonnes per hectare). An application rate describes how much of an input like fertilizer or seed is applied per unit of land area. Both are commonly expressed using the same kind of mass-per-area units.
