About this conversion
Gallons per square meter and Milligrams per hectare are units used in the Universal Converter agriculture category. Gallon per Square Meter (gal/m2): Liquid application rate. Milligram per Hectare (mg/ha): Mass application rate.
Gallons per square meter belongs to the liquid application rate family, while Milligrams per hectare 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.
