Question

what is the difference between 5g and 5.0 g?​

Answer 1

Answer:

A = 5 gm means the quantity A is measured with an instrument or scale having a least count of 1gm.

A = 5.0 gm means the scale of weighing machine is calibrated much better. It has a least count of 0.1 gm. It's accuracy is better.

If there is a mistake in measurement then using the first method/scale, we could get 4 gm or 6 gm. But with second measurement we could get 5.1 or 4.9 gm.

Thus the accuracy of measurement is different.
