If I have a human specimen with a WEIGHT of: 61.14 kg, and then divide by 9.8 m/s^2 (g), then the specimen has a MASS of: 6.24 kg. So...is this wrong, or right? Is there one type of kg for weight, and another for mass? As I understand it: weight is a measure of force, whereas mass is a measure of matter. So...is this wrong, or right?
