How to convert pounds and kilograms
pounds = kilograms ÷ 0.45359237
One pound is exactly 0.45359237 kilograms, so a quick estimate is to halve the pounds and take off another tenth. An 1,100 lb horse weighs 499 kg.
Where horse owners need it
Weight appears in many places in horse care. A feed label may give a ration in pounds, a veterinary dose table may use milligrams per kilogram of body weight, and a foreign article may list a horse's weight in kilograms. If you do not know your horse's weight, estimate it with the horse weight calculator, which gives pounds and kilograms.
Tons and tonnes
A U.S. ton is 2,000 pounds (about 907 kg), and a metric tonne is 1,000 kilograms (about 2,205 lb). When you order sand, hay or footing by the ton, check which one the supplier means. The arena sand calculator and the hay calculator both work in pounds and tons.
Where these numbers come from
Standard conversion factors based on international definitions (the international foot, avoirdupois pound and U.S. gallon). Horse figures are typical ranges from veterinary and extension guidance, and they vary by horse. See how we calculate and the disclaimer.
