Even seeing the pigs everyday their gowth is clearly visible. Today after their weekly measure we decided to use the formula to calculate their weight! So with pen, paper and tape measure we carefully took down the details measuring first the heart girth, just behind the front legs, then the length from the base of the ears to the base of the tail. These measurements were then taken to the kitchen table and with calculator in hand and lots of advice from everyone around (maths not being my strong point) I followed the formula.
1. square the heart girth which was 36
2. multiply the girth by the length which was 44
3.divide by 400.
Now we have the weight in pounds. We made that just over 10 stone ! If anyone can be bothered to work it out and see if I'm right please comment with your answere's.
