The numeric factor shown (4.046856422e-06) is calculated from each unit's defined scale, but Grams per square kilometer and Cubic meters per acre belong to different agriculture measurement families (mass application rate vs liquid application rate). A direct physical conversion between the two requires them to share the same measurement family; use this figure as a scale reference rather than a like-for-like agronomic equivalence.
Where is the grams per square kilometer unit commonly used?
It is commonly used in agriculture and agronomy for mass application rate calculations such as field records, fertilizer and seed planning, or irrigation and yield tracking.

About this conversion
Grams per square kilometer and Cubic meters per acre are units used in the Universal Converter agriculture category. Gram per Square Kilometer (g/km2): Mass application rate. Cubic Meter per Acre (m3/ac): Liquid application rate.
Grams per square kilometer belongs to the mass application rate family, while Cubic meters per acre belongs to the liquid 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.
