Relation between different scales

  • The relationship between different scales of temperature in heat and thermodynamics can be established through conversion formulas. 
  • The most common temperature scales used in heat and thermodynamics are Celsius, Fahrenheit, and Kelvin.

CELSIUS AND FAHRENHEIT CONVERSION


The relationship between Celsius (C) and Fahrenheit (F) can be established using the formula:


F = (9/5)C + 32

The relationship between Celsius (C) and Kelvin (K) can be established using the formula:


K = C + 273.15

The relationship between Fahrenheit (F) and Kelvin (K) can be established using the following two conversion formulas:


C = (F - 32) * (5/9)
K = (F + 459.67) * (5/9)


  • It's important to note that the Kelvin scale is an absolute scale, meaning it starts at absolute zero, which is the temperature at which all matter has zero thermal energy.
  • On the other hand, the Celsius and Fahrenheit scales are relative scales, with their zero points defined as the freezing and boiling points of water under standard atmospheric conditions.
