Well all you must remember is Kg is a measure of weight and a newton is a measure of force (I think lol) but if you convert the 9Kg to 9Kgf this will give about 88.25 newtons. if that helps at all lol

Youve just got to go with force measurements thats why i used the torque rench as it gets a bit complicated if you start trying to convert force over to weight and visa versa i suppose thats why newtons measure is still in use today...
