About this conversion
Acre and Pounds per square meter are units used in the Universal Converter agriculture category. Acre (ac): An international acre is 4,046.8564224 square meters. Pound per Square Meter (lb/m2): Mass application rate.
Acre belongs to the area family, while Pounds per square meter belongs to the mass application rate family.
