Webb2 sep. 2024 · A thermometer is used to measure the temperature of a person, not height. Height of a person can be measured by a measuring tape or ruler which has scale for length. Hence, the above statement is incorrect. iv. The SI unit of measuring length is centimetre. The SI unit of measuring length is metre, and not centimetre. Webb15 sep. 2024 · The SI unit of Temperature is Kelvin. As shown below, water is boiling on a gas burner in a utensil. It can be observed that heat energy is transferred from the gas burner to the water when boiled. The water gets boiled at 100 °C, which is its temperature, and is measured with the help of a thermometer. Heat.
