Least count is the smallest measurement that could be done by the instrument. In ordinary scale we have every cm gap seems divided into ten equal parts. Hence the least count will be 1/10 of cm. Same way in the spring balance the markings might have been made in different ways. Suppose if 100 g marked gap is divided into 5 equal parts then the least count woud be 100/5 = 20 g.
If suppose 50 g marked gap is divided into 4 equal parts, then the least count becomes 12.5 g. So it depends on the calibration of the scale.

LC is the least physical quantity attained by a instrument in case of spring balance f 1000gf capacity and 10 div /100 lc=10gf coz its the least one can attain
zerro error in a spring balance affects the accuracy in the weight. To find zero error in spring balance, you have to first find the least count of the spring balance and then suspend it freely, if the outcome is +1, the zero error is +1 and if it is -1 ,the zero error is -1.

The importance of least count ( the highest degree of accuracy of measurement) helps calculate the margin of errors when doing measurements.
In my opinion, Least count of Spring Balance is very less to measure valuable metal like Gold.
The least count of the balance has been given in the balance itself.Otherwise place the weight in the balnce and check the result in the balance.If the result shows for 1kg i.e 1.001 then the lease count of the balance is 0.001kg. S.Kumar Asst.Manager QA Medopharm bangalore
