Precision Measuring Instruments
This simulation compares the precision of different measuring devices based on their least count (the smallest measurement they can make). The most precise device has the smallest least count. Select an instrument to visualize its measurement capability or compare all instruments to see which is most precise.

Instrument Analysis:
Vernier Calipers with 20 divisions has a least count of 0.01 cm.
Least count = 1 main scale division - 1 vernier scale division = 1mm - 0.9mm = 0.1mm = 0.01cm
Comparison Results:
The most precise instrument is the one with the smallest least count value.
