About Converting Kilograms per Square Kilometer to Grams per Square Meter
Kilogram 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 = kilograms per square kilometer × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per square kilometer equals 0.000001 base units, and 1 gram per square meter equals 0.001 base units, so dividing one by the other gives the direct kilogram per square kilometer-to-gram per square meter factor of 0.001.
Simple example
1 kg/km2 × 0.001 = 0.001 g/m2
1 kilogram per square kilometer = 0.001 grams per square meter.
Real-world example
100 kg/km2 × 0.001 = 0.1 g/m2
100 kilograms per square kilometer = 0.1 grams per square meter.

What is a kilogram per square kilometer?
Kilogram per Square Kilometer (kg/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 kilogram per square kilometer to gram per square meter conversion exact?
Yes. Both kilogram per square kilometer and gram per square meter are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
