How do you Weigh a Horse

The easiest way would be to use a weighing scale, but if that is not available, you can use the formula method by measuring the heart girth and body length in inches with a weight tape. The bodyweight of a full-grown horse can then be calculated from the following formula:

(Heart Girth X Heart Girth X Body Length)/300 = Bodyweight (in lbs)
