About Converting Metric tons per Square Kilometer to Metric tons per Acre
Metric ton per Square Kilometer and Metric ton per Acre 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
metric tons per acre = metric tons per square kilometer × 0.0040468564224
This factor comes from each unit's defined relationship to the category's base unit: 1 metric ton per square kilometer equals 0.001 base units, and 1 metric ton per acre equals 0.247105381467 base units, so dividing one by the other gives the direct metric ton per square kilometer-to-metric ton per acre factor of 0.0040468564224.
Simple example
1 t/km2 × 0.004046856422 = 0.0040468564 t/ac
1 metric ton per square kilometer = 0.0040468564 metric tons per acre.
Real-world example
100 t/km2 × 0.004046856422 = 0.4046856422 t/ac
100 metric tons per square kilometer = 0.4046856422 metric tons per acre.

What is a metric ton per square kilometer?
Metric ton per Square Kilometer (t/km2) is a unit of agriculture.
What is a metric ton per acre?
Metric ton per Acre (t/ac) is a unit of agriculture.
Is the metric ton per square kilometer to metric ton per acre conversion exact?
Yes. Both metric ton per square kilometer and metric ton per acre are defined by fixed standards rather than physical artifacts, so the factor of 0.004046856422 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.
