Question

Convert a force of 5 kg-wt into SI unit of force .

Answer 1

Kilogram is unit of mass while Newton is unit of force, so you can't convert kg into Newton and vice-versa. However, force can also be expressed in the unit of kilogram-force (kg-f). 1 kg-f is the weight corresponding to 1 kg mass. Thus, 1 kg-force is equal to g Newton. If you take g=10m/s2 and assuming your mass is 5kg, you can say that your weight is 5kg-f or 50 N.in force unit
