Convert between all major agricultural units — land area, crop weight and bushels, grain storage volume, irrigation flow and pressure, application rates, and livestock units. Dynamic bushel weights adjust by commodity.

1 hectare = 2.47105 acres. Conversely, 1 acre = 0.404686 hectares. A standard quarter section of 160 acres equals 64.75 hectares.
A bushel of corn weighs 56 pounds (25.40 kg) per USDA standard test weight. Soybeans and wheat are 60 lbs/bu (27.22 kg). Barley is 48 lbs/bu. Oats are 32 lbs/bu. Use the commodity selector in this converter to apply the correct weight automatically.
1 liter per second = 15.85 US gallons per minute (GPM). Center pivot irrigation systems in the US are typically rated in GPM, while metric regions use L/s or m³/h. 1 m³/h = 4.40 GPM.
A short ton (US ton) = 2,000 pounds = 907.18 kg. A metric tonne = 1,000 kg = 2,204.62 pounds. A long ton (UK) = 2,240 pounds = 1,016.05 kg. When trading grain internationally, metric tonnes are the standard. Always confirm which ton is being used in contracts.
Multiply lb/acre by 1.12085 to get kg/ha. For example, 100 lb/acre × 1.12085 = 112.09 kg/ha. To convert kg/ha back to lb/acre, multiply by 0.89218.
1 acre-foot = 12 acre-inches. An acre-foot is the volume of water needed to cover 1 acre to a depth of 1 foot (325,851 US gallons / 1,233.48 m³). Irrigation is commonly measured in acre-inches per season or per application.
One Animal Unit (AU) is defined as a 1,000-pound mature beef cow. Other livestock are expressed as fractions or multiples: 1 dairy cow ≈ 1.4 AU, 1 horse ≈ 1.25 AU, 1 sheep ≈ 0.2 AU, 1 market hog ≈ 0.4 AU. AU is used in grazing management to calculate stocking rates and carrying capacity.
1 L/ha = 0.1069 US gal/acre. Conversely, 1 gal/acre = 9.354 L/ha. This conversion is commonly needed when calibrating sprayers using metric application rates for US equipment or vice versa.
