The least count is the value of the smallest scale division of the measurement instrument. Example: a ruler with marks 1 millimeter apart has a least count of 1 millimeter The least count of an instrument is the size of the smallest scale division on the instrument. The smaller the least count the more precise the instrument is said to be. For example a metric ruler which has millimeter marks has a least count of 1 mm or 0.1 cm. and when properly used it can make more precise measurements than one with centimeter marks.
Vernier scale reading: 0.02 cm. Measurement: 10.02 cm. Now, we shall try with zero error. If you are not familiar on how to handle zero error for vernier calipers, I suggest that you read up on Measurement of Length. The reading on the top is the measurement obtained and the reading at the bottom is the zero error. Find the actual measurement. (Meaning: get rid of the zero error in the measurement or take into account the zero error). Measurement with zero error: 3.34 cm.
