About Converting Grams per Square Kilometer to Kilograms per Hectare
Gram per Square Kilometer and Kilogram 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
kilograms per hectare = grams per square kilometer × 0.00001
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 kilogram per hectare equals 0.0001 base units, so dividing one by the other gives the direct gram per square kilometer-to-kilogram per hectare factor of 0.00001.
Simple example
1 g/km2 × 0.00001 = 0.00001 kg/ha
1 gram per square kilometer = 0.00001 kilograms per hectare.
Real-world example
100 g/km2 × 0.00001 = 0.001 kg/ha
100 grams per square kilometer = 0.001 kilograms per hectare.

Reverse conversion: Kilogram per Hectare to Gram per Square Kilometer
0.00001 kg/ha × 100000 = 1 g/km2
0.00001 kilograms per hectare = 1 gram per square kilometer.
grams per square kilometer = kilograms per hectare × 100000

Understanding the Kilogram per Hectare
Kilogram per Hectare (kg/ha) measures agricultural application/yield rate. One kilogram of material per hectare (10,000 square meters) of land. It is classified as a metric agricultural rate unit.
Where it's used: The standard international unit for fertilizer, pesticide, and seed application rates outside the US
Uses of the Kilogram per Hectare today
- Fertilizer and pesticide application-rate labeling
- Crop yield reporting in most countries outside the US
- Agronomy research and soil-nutrient planning
Kilogram per Hectare — sources
- FAO Statistical Yearbook methodology notes — Standard unit for reporting agricultural input and yield rates internationally.

Frequently asked questions
How many kilograms per hectare are in 1 gram per square kilometer?
1 gram per square kilometer equals 0.00001 kilograms per hectare, using the exact defined conversion factor rather than an estimate.
How do I convert gram per square kilometer to kilogram per hectare?
Multiply the gram per square kilometer value by 0.00001. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per hectare back to gram per square kilometer?
Use the reverse factor: 1 kilogram per hectare equals 100,000 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 kilogram per hectare?
Kilogram per Hectare (kg/ha) measures agricultural application/yield rate. One kilogram of material per hectare (10,000 square meters) of land. It is classified as a metric agricultural rate unit.
Is the gram per square kilometer to kilogram per hectare conversion exact?
Yes. Both gram per square kilometer and kilogram per hectare are defined by fixed standards rather than physical artifacts, so the factor of 0.00001 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.
