What does the scale value of scale mean in physics?
The fractional value of the scale used is 1mm, in which the exact value is 25.6cm and the estimated value is 0.0 1cm.

The dividing value is the minimum value that can be measured by measuring instruments. The division value is also the value of each cell.

The measured value consists of an accurate value and an estimated value. The last digit is the estimated value, and the estimated value can only be one digit.

Example: 25.60cm and 25.6cm are mathematically equivalent, but their physical meanings are different.

25.60cm=256.0mm, which unifies the units of measured values and makes their values become decimal places. See what units it uses,

What units are used to divide values?

256.0mm, the dividing value of the scale is 1mm (it can be accurate to 1mm with this scale, and it will be estimated if it is less than 1mm).

The exact value is 256mm and the estimated value is 0.0 mm

25.6cm, the graduation value of the scale is 1cm (with this scale, it can be accurate to 1cm, and it will be estimated if it is less than 1cm).

The exact value is 25cm and the estimated value is 0.6cm.
