Understanding the Kilogram per Acre
Kilogram per Acre (kg/ac) measures agricultural application/yield rate. A mathematically valid way to express an agricultural application or yield rate in kilograms per acre. It is classified as a mixed metric/US customary rate unit.
Uses of the Kilogram per Acre today
- Can be used to express US agricultural application or yield rates in metric mass — in practice, pounds per acre (US customary) and kilograms per hectare (international/metric) are the specific unit pairings most commonly seen on US agricultural references
Kilogram per Acre — sources
- US agricultural extension fertilizer-rate references — US agricultural sources typically pair pounds with acres or kilograms with hectares rather than kilograms with acres directly.
