For example, if your mass is 40kg, it will show 40kg in the balance. You can either say your mass is 40kg or tour weight is 40 kgf.
kgf is the unit of weight.
1 kgf = weight of an object whose mass is 1 kg
=> 1 kgf = 1 × 9.8 = 9.8 N
So when the balance shows 40 kg, you can infer:
--> the mass is 40 kg
--> the weight is 40 kgf
--> or weight = 40×9.8 = 392 N
Explanation:
As a result, our apparent weight becomes less than the true weight. The weighing machine measures this apparent weight and hence the mass indicated by it is less than the actual mass. Our actual mass will be more than 42 kg
