The smallest temperature value a thermometer can read is called the least count. It refers to the smallest division or increment on the thermometer’s scale. For example, in a thermometer with a least count of 1°C, it can measure temperature changes as small as 1°C. This value is important for determining the accuracy of the thermometer, as a smaller least count allows for more precise readings.
