About this chapter

The temperature of a body is a reliable measure of how hot or cold it is. Our sense of touch is not reliable — the same water in container B feels cool to a hand coming out of warm water and warm to a hand coming out of ice-cold water. A thermometer is the device that measures temperature. A clinical thermometer (today usually a digital one) measures human body temperature; a laboratory thermometer is used for everything else. The three common scales are the Celsius scale (unit degree Celsius, °C ), the Fahrenheit scale (unit degree Fahrenheit, °F ) and the Kelvin scale (unit kelvin, K ). The SI unit of temperature is kelvin , and temperature in K = temperature in °C + 273.15. The normal temperature of a healthy human body is taken to be 37.0 °C , which is the same as 98.6 °F . It is an av
