About this conversion
Gallons per square kilometer and Milligrams per square meter are units used in the Universal Converter agriculture category. Gallon per Square Kilometer (gal/km2): Liquid application rate. Milligram per Square Meter (mg/m2): Mass application rate.
Gallons per square kilometer belongs to the liquid application rate family, while Milligrams per square meter belongs to the mass application rate family. The agriculture converter is dimension-aware, so a direct conversion between units from different families is not agronomically meaningful without extra context (such as a crop's bulk density or field application details); the scale factor above is provided purely for numeric reference.
