About Converting Metric tons per Square Kilometer to Grams per Square Meter
Metric ton per Square Kilometer and Gram 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
grams per square meter = metric tons per square kilometer × 1
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per square kilometer equals 0.001 base units, and 1 gram per square meter equals 0.001 base units, so dividing one by the other gives the direct metric ton per square kilometer-to-gram per square meter factor of 1.
Simple example
1 t/km2 × 1 = 1 g/m2
1 metric ton per square kilometer = 1 gram per square meter.
Real-world example
100 t/km2 × 1 = 100 g/m2
100 metric tons per square kilometer = 100 grams per square meter.

Frequently asked questions
How many grams per square meter are in 1 metric ton per square kilometer?
1 metric ton per square kilometer equals 1 gram per square meter, using the exact defined conversion factor rather than an estimate.
How do I convert metric ton per square kilometer to gram per square meter?
Multiply the metric ton per square kilometer value by 1. The converter above does this instantly to whatever precision you set.
How do I convert gram per square meter back to metric ton per square kilometer?

What is a metric ton per square kilometer?
Metric ton per Square Kilometer (t/km2) is a unit of agriculture.
What is a gram per square meter?
Gram per Square Meter (g/m2) is a unit of agriculture.
Is the metric ton per square kilometer to gram per square meter conversion exact?
Yes. Both metric ton per square kilometer and gram per square meter are defined by fixed standards rather than physical artifacts, so the factor of 1 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.
