'Least count' of a thermometer is the 'minimum reading' that can be read in degrees.
EXPLANATION:
The least count for a 'clinical thermometer' is 0.2 degrees. This is because there are '5 subdivisions' of 1 division. Likewise, if a thermometer has 20 divisions and calibrations are 10,20,30 and so on, the least count of thermometer would be 0.5. The least count can be 'calculated' by dividing the smallest calibration on the thermometer by the 'total number of divisions'.
