The Horse Weight Estimate calculator estimates the weight of a horse based on the measurement of the horse's girth (G) and a chest to tail measurement (CTM).
INSTRUCTIONS: Choose units and enter the following:
- (G) Girth of Horse
- (CTM) Chest to Tail measurement
Horse Weight Estimate (W): The calculator returns the weight in pounds (lbs). However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
How much does a horse weigh? Unless you have very large scales, one must make an estimation. A very common formula for the weight estimate of a horse is a function of the length around the girth, and the length from the chest to the tail. This is used to make a rough estimate of the volume of horse flesh (skin, muscle, bone, fluids) and applies that to estimate the weight.
This calculation replaces the need for a horse weight tape. The formula used in this Horse Weight calculator is:
`W = (G^2 * CMT) /12000`
where:
- W is the weight of the horse in Kilograms
- G is the length of the girth in centimeters
- CMT is the chest to tail measurement in centimeters.
The calculator makes the conversions from inches to centimeters and kilograms to pounds automatically.
Horse and Stable Calculators
- Weight of Horse: This is based on the girth and length of the horse.
- Daily Hay Weight for a Horse: This is based on the horse's weight and percent of body weight.
- Daly Bales of Hay for a Horse: This is based on the horse's weight, percent of body weight and weight of bales.
- How Long Hay will Last: This is based on the number of bales in the loft, number of horses, and the bales per day for the horses.
- How Much Hay: This estimates the amount of hay needed for a period of time based on the daily consumption per animal, the number of animals and the duration.
