About Converting Grams per Square Kilometer to Grams per Hectare
Gram per Square Kilometer and Gram 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
grams per hectare = grams per square kilometer × 0.01
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 gram per hectare equals 1e-7 base units, so dividing one by the other gives the direct gram per square kilometer-to-gram per hectare factor of 0.01.
Simple example
1 g/km2 × 0.01 = 0.01 g/ha
1 gram per square kilometer = 0.01 grams per hectare.
Real-world example
100 g/km2 × 0.01 = 1 g/ha
100 grams per square kilometer = 1 grams per hectare.

What is a gram per hectare?
Gram per Hectare (g/ha) is a unit of agriculture.
Is the gram per square kilometer to gram per hectare conversion exact?
Yes. Both gram per square kilometer and gram per hectare are defined by fixed standards rather than physical artifacts, so the factor of 0.01 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.
