# What is the difference between resolution and least count of a measurement? [closed]

1.What is the difference between resolution and least count of a measurement?

1. In my physics book the statement of a question is as under :

" The time taken by a pendulum for 100 oscillations is found to be 90 seconds using a wrist watch of 1second resolution."

I don't know how to interpret this statement .

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

This means the accuracy of the measurement is limited by the resolution or the least count of the wrist watch. If you take a measurement that probably would be like $$8.5 s$$, the wristwatch would either give $$8 s$$, or $$9 s$$, since the wristwatch cannot produce decimals.
