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
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.
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.
for a levelling staff the least count is 0.01in and in m 0.005m
the least count of travelling microscope = 0.001 cm

0.1g
least count of a spectrometer is equal to 1' (one minute)
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
Smallest value of a physical quantity which can be measured accurately by an instrument is called least count
the least count of the device must be noted first. the uncertainty of this will be the least count divided by 2. so if its is 0.1 then it will be 0.05
Its least count is 0.001g i.e minimum among other balances.Its precision is maximum due to minimum least count.So electronic balance is an accurate balance.
In my opinion, Least count of Spring Balance is very less to measure valuable metal like Gold.

43 in case of double so it"ll be 86 for triple , Jk that was just crzy.
least count of scale is 1mm
