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