Weighing balance

what is the difference between least count and minimum range?

Least count means the balance which displays the minimum value.
Generally, balances display either odd or even digits (i.e; 0.01 or 0.02) depending on the capacity of the balance.
If the balance displays 0.01, then it will be the least count.
By using the least count value, we can know the minimum operating range of the respective balance.
Minimum operating range: Multiply the Least count value with number 50.
In above case, if the balance displays 0.01 as minimum reading, then it’s operating range will be 0.01 x 50 = 0.5Kg.
