Does accuracy depend on the least count of instruments?

Yes , The accuracy of an instrument does depend on its least count. Least count of the instrument can determine the smallest measurement it can take without any errors, hence smaller the least count of an instrument is ,better is its accuracy. read more

The least count is related to the resolution of an instrument. For an instrument to be accurate or precise to some level, it should have enough resolution (i.e. least count). But an instrument with some resolution may not be accurate or precise to that level. They are related in this sense. read more

Accuracy, Precision of Instruments and Errors in Measurement There is only a limit up to which measurements can be made with a measuring instrument. This limit is called the least count of the instrument. For example, a metre rod can measure length accurately up to 0.1 cm, whereas vernier caliper can measure length accurately up to 0.01 cm. read more
