For temperatures the Celsius scale is generally used in the scientific community and in much of the world, though the Fahrenheit scale is still used in the USA. The Celsius scale has 0° as the freezing point of water and 100° as the boiling point of water, a difference of 100°. On the Fahrenheit scale the freezing point of water is 32° and the boiling point 212°, a difference of 180°. For conversions between the two scales, the following equation can be used: F−32180=C100

The universal symbol for temperature is: T. The unit for temperature, in the SI, or metric, realm is °C or degrees Celsius. In the Celsius temperature scale system, 0°C represents the freezing point of water. The unit for temperature, in the US, or imperial, realm is °F or degrees Fahrenheit. On the Fahrenheit temperature scale system, 32°F or degrees Fahrenheit represents the freezing point of water. The formulas used for conversion of temperature from metric to US realm, and vice versa, are as follows:

What are temperature, heat, and power? Temperature is a measure of how hot or cold an object is. Fahrenheit (F) is the temperature scale used for British units while Celsius (C) is the metric temperature scale. Centigrade (C) is the same as Celsius. For the Fahrenheit scale, 32 is the freezing point of water and 212 is the boiling point of water. For the Celsius scale, 0 is the freezing point of water and 100 is the boiling point. The equation which relates the two temperature scales is F = 1.8 * C + 32.

Air-specific heat cpa can be calculated by eq. (13) (Zare et al. 2006) and air density ρa can be calculated by eq. (14) (Nazghelichi, Aghbashlo, and Kianmehr 2011) which are valid for the range of −17.78°C to 48.89°C (0-120°F) (Brooker 1967),
