This basic calculator was built specifially for people training to lift the Dinnie stones using rings with weight-loadable pins. It calculates the weight for each pin using the weight ratio of the original Dinnie Stones.
The total weight of the Dinnie Stones is 332.49kg. The large stone is 188.02kg, and the smaller stone is 144.47kg - a ratio of about 1:0.7684. This calculator rounds to 2 decimal places.
