Farmers often need to convert measurements of weight per area for fertilizers, seeds, or crops. Two common units used are:
- Kilograms per hectare (kg/ha) — metric unit used widely around the world.
- Pounds per acre (lb/acre) — imperial unit commonly used in the USA and some other countries.
Why Convert?
If you have a value in kg/ha but your equipment or recommendations are in lb/acre, you need to convert to apply the right amount.
Conversion Basics
1 hectare = 2.47105 acres
1 kilogram = 2.20462 pounds
Conversion Formula

If you have 100 kg/ha, the conversion to pounds per acre is:
100×0.89218=89.22 lb/acre
