# What is the least count of a spring balance?

Solution

## Determine the least count of a spring balance.A least count of an instrument is the smallest value of a physical quantity that can be measured properly by using the instrument. For example, with a spring balance with a range of $0to25$ kilograms, each kilogram on the scale is split into ten equal pieces. Therefore, the minimum value this could measure is one hundred grams, which may be calculated as follows:Measurement $=1kg$Total Number of divisions $=10$Least count $=\left(\frac{1}{10}\right)=0.1kg\left(or100g\right)$Mostly as result, the lowest count of this instrument is $100g$. Similarly, the least counts of different spring balances with varied ranges may be discovered. Hence, the least count of a measurement device is the smallest physical amount that can be measured reliably using the instrument.
