How to Calculate Pig Weight

You can calculate a pig's weight without the use of an expensive livestock scale.

Buying a scale that can weigh pigs and other farm animals can be an expensive investment. If you need to calculate the weight of a pig and do not have a livestock scale at your disposal, it is possible to obtain a rough estimate of your pig's weight without the use of a scale. You will only need simple items that you can find around your house.

Things You'll Need

• Fabric measuring tape
• Calculator

Instructions

1. Measure the pig's heart girth. Place the fabric measuring tape around the pig, just behind the front legs. Note the pig's circumference in inches.

2. Measure the pig's length in inches. Start at the base of the pig's ears and measure to the base of its tail. Note the pig's length.

3. Calculate the pig's girth measurement. To calculate the girth, you will square the heart girth measurement. For example, if the pig had a heart girth of 44 inches, you will multiply 44 x 44, and calculate a girth measurement of 1936.

4. Multiply the pig's girth measurement by its length. If our example pig had a length measurement of 39 inches, you would multiply 1936 x 39 and get a total of 75,504.

5. Divide your total by 400. This is your pig's weight in pounds. Following our example, we would divide 75,504 by 400, to calculate a total weight of 188.76 lbs.
