Question

What is the least count of your wrist watch? Is it same for all kinds of watches?

TNSCERT Class 9 General Science Ch 5 Measurement and Measuring Instruments

Answer 1

Thanks for asking the question.
Least count of a device is actually the smallest measurement it can take. In case of analogue watches which include the common clocks and wrist watches(not digital) the least count is one second. However in case of digital watches the least count may vary because many watches are designed to measure time in milli seconds and micro seconds.
Hope it helps.
