Everybody knows scale device is measuring the kg. However, I am not sure it is physically possible or not.
Mass and weight are not the same things. Gravity (m/s^2) affects everything.
For this reason, while we are measuring a sample by scale device, gravity affects to the sample, which we put on the scale device. Also, gravity affects to the scale device too but this forces are affacts to the same point and at the same direction. Thus, this factor cannot be neglectable.
Therefore, in my opinion, we are not measuring kg, actually we are measuring Newton (m/s^2) because of gravity.
If we use equal arm scale, we can measure the real mass, because gravity factor is equal at the both arm. Thus, gravity factor can be neglectable (Remember Static Lessons), but we cannot say this for other scales.
Some scale devices have electronic parts.
Are they calculate the real mass by using gravity factor ( 9,80665 m/s^2), after that, they shows the real mass in their screen?
If it is not, how we are measuring the real mass with scale devices?
Waiting for your explaination.
Thank you.
