About Converting Grams per Square mile to Kilograms per Hectare
Gram per Square mile 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 mile × 0.00000386102158542
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per square mile equals 3.861022e-10 base units, and 1 kilogram per hectare equals 0.0001 base units, so dividing one by the other gives the direct gram per square mile-to-kilogram per hectare factor of 0.00000386102158542.
Simple example
1 g/mi2 × 0.000003861021585 = 0.000003861 kg/ha
1 gram per square mile = 0.000003861 kilograms per hectare.
Real-world example
100 g/mi2 × 0.000003861021585 = 0.0003861022 kg/ha
100 grams per square mile = 0.0003861022 kilograms per hectare.

What is a gram per square mile?
Gram per Square mile (g/mi2) 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 mile to kilogram per hectare conversion exact?
Yes. Both gram per square mile and kilogram per hectare are defined by fixed standards rather than physical artifacts, so the factor of 0.000003861021585 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.
