I did the math myself – I have gotten pretty good at converting between kg and lb – (14 x 2.2 = just over 30 pounds). Good on her.
For you those playing at home:
1 kilogram = 2.20462262 pounds
1 kilogram = 0.157473044 stones
1 stone = 14 pounds
Next I think I will start measuring my runs in furlongs (1 furlong = 10 chains which is 0.201168 kilometers or 660 feet). I think running a 500 chain race sounds pretty cool (just over 10k or 6 and a quarter miles).
