About Converting Metric tons per Hectare to Grams per Square Kilometer
Metric ton per Hectare 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. Metric ton per Hectare is most often used for national and international crop yield statistics (fao reporting).
Formula
grams per square kilometer = metric tons per hectare × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per hectare equals 0.1 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 hectare-to-gram per square kilometer factor of 100000000.
Simple example
1 t/ha × 100000000 = 100,000,000 g/km2
1 metric ton per hectare = 100,000,000 grams per square kilometer.
Real-world example
100 t/ha × 100000000 = 10,000,000,000 g/km2
100 metric tons per hectare = 10,000,000,000 grams per square kilometer.
Conversion table
| Metric ton per Hectare (t/ha) | Gram per Square Kilometer (g/km2) |
|---|---|
| 1 t/ha | 100,000,000 g/km2 |
| 5 t/ha | 500,000,000 g/km2 |
| 10 t/ha | 1,000,000,000 g/km2 |
| 50 t/ha | 5,000,000,000 g/km2 |
| 100 t/ha | 10,000,000,000 g/km2 |
| 500 t/ha | 50,000,000,000 g/km2 |
Reverse conversion: Gram per Square Kilometer to Metric ton per Hectare
1 g/km2 × 1e-8 = 1e-8 t/ha
1 gram per square kilometer = 1e-8 metric tons per hectare.
metric tons per hectare = grams per square kilometer × 1e-8

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

Frequently asked questions
How many grams per square kilometer are in 1 metric ton per hectare?
1 metric ton per hectare equals 100,000,000 grams per square kilometer, using the exact defined conversion factor rather than an estimate.
How do I convert metric ton per hectare to gram per square kilometer?
Multiply the metric ton per hectare value by 100000000. The converter above does this instantly to whatever precision you set.
How do I convert gram per square kilometer back to metric ton per hectare?
Use the reverse factor: 1 gram per square kilometer equals 1e-8 metric tons per hectare. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a gram per square kilometer?
Gram per Square Kilometer (g/km2) is a unit of agriculture.
Is the metric ton per hectare to gram per square kilometer conversion exact?
Yes. Both metric ton per hectare and gram per square kilometer are defined by fixed standards rather than physical artifacts, so the factor of 100000000 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.
Where is the metric ton per hectare still used today?
The standard international unit for crop yield reporting outside the US (FAO and most national agricultural statistics)
