IMPERIAL – Weight of your pig in POUNDS
Obtain a fabric measuring tape or a piece of string to use as a measure. If using string mark the dimensions on the string and then measure the dimensions using a steel tape measure.
Place the tape/string under the pig just behind the front legs and measure the circumference of the pigs girth in inches. This measurement is known as the Heart Girth (see graphic)
Then measure the Length of the pig along its back from the base of its ears to the base of its tail, again in inches. (see graphic)
To calculate the pigs weight, first square the Heart Girth to get the Girth Result.
Now Multiply the Girth Result by the Length and DIVIDE by 400.
You now have the weight of your pig in Pounds.
Example:
Porky Pig has a Heart Girth of 50 inches and a Length of 40 inches.
Squaring the Heart Girth (50 x 50) = 2500 = Girth Result
Multiply the Girth Result (2500) by the Length (40) and divide by 400 = 250 Pounds.
METRIC VERSION – Weight of your pig in KILOGRAMMES
Use the same procedure as above taking your measurement in Meters.
Then use the following formula.
Square the Heart Girth to get the Girth Result.
Now Multiply the Girth Result by the Length and MULTIPLY by 69.3
You now have the weight of your pig in Kg.
