Temperature Measurement
Temperature is a measure of degree of hotness or coldness of an object. Units of Temperature The two most common temperature scales are Fahrenheit (°F) and Celsius (°C) . Water freezes at 32°F and boils at 212°F. The Celsius scale uses the same reference points only it defines the freezing point of water as 100°C and the boiling point as 100°C. We see from these definitions that a Fahrenheit degree is 9/5 of a Celsius degree and is offset by 32°. To convert between these scales we use the following formulas: Temperature is most commonly measured by Resistance Temperature Devices (RTD) and Thermo- couples, and to a lesser degree Infrared (IR).
