About Converting Grams per Square Kilometer to Metric tons per Hectare
Gram per Square Kilometer and Metric ton per Hectare 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 hectare = grams per square kilometer × 1e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per square kilometer equals 1e-9 base units, and 1 metric ton per hectare equals 0.1 base units, so dividing one by the other gives the direct gram per square kilometer-to-metric ton per hectare factor of 1e-8.
Simple example
1 g/km2 × 1e-8 = 1e-8 t/ha
1 gram per square kilometer = 1e-8 metric tons per hectare.
Real-world example
100 g/km2 × 1e-8 = 0.000001 t/ha
100 grams per square kilometer = 0.000001 metric tons per hectare.

Understanding the Metric ton per Hectare
Metric ton per Hectare (t/ha) measures agricultural yield/application rate. One tonne (1,000 kg) of material per hectare (10,000 square meters) of land — the standard way crop yield is reported internationally. It is classified as a metric agricultural rate unit.
Where it's used: The standard international unit for crop yield reporting outside the US (FAO and most national agricultural statistics)
t/ha vs. kg/ha. The same quantity at different scales: 1 t/ha equals 1,000 kg/ha. t/ha is typically used for whole-field yield reporting, while kg/ha suits precise fertilizer or pesticide application rates.
Uses of the Metric ton per Hectare today
- National and international crop yield statistics (FAO reporting)
- Agronomy research and field-trial yield comparisons
- Large-scale fertilizer and soil-amendment application-rate planning

Frequently asked questions
How many metric tons per hectare are in 1 gram per square kilometer?
1 gram per square kilometer equals 1e-8 metric tons per hectare, using the exact defined conversion factor rather than an estimate.
How do I convert gram per square kilometer to metric ton per hectare?
Multiply the gram per square kilometer value by 1e-8. The converter above does this instantly to whatever precision you set.
How do I convert metric ton per hectare back to gram per square kilometer?
Use the reverse factor: 1 metric ton per hectare equals 100,000,000 grams per square kilometer. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per square kilometer?
Gram per Square Kilometer (g/km2) is a unit of agriculture.
What is a metric ton per hectare?
Metric ton per Hectare (t/ha) measures agricultural yield/application rate. One tonne (1,000 kg) of material per hectare (10,000 square meters) of land — the standard way crop yield is reported internationally. It is classified as a metric agricultural rate unit.
Is the gram per square kilometer to metric ton per hectare conversion exact?
Yes. Both gram per square kilometer and metric ton per hectare are defined by fixed standards rather than physical artifacts, so the factor of 1e-8 used above is exact to as many digits as you choose to display.
What is the difference between t/ha vs. kg/ha?
The same quantity at different scales: 1 t/ha equals 1,000 kg/ha. t/ha is typically used for whole-field yield reporting, while kg/ha suits precise fertilizer or pesticide application rates.
