The measurement of temperature in the laboratory is unsophisticated in its approach, and at the same time complicated.

Temperature is best defined as the level of thermal energy, where temperature is the driving force of thermodynamic flow.

Three of the most commonly used scales for measuring temperature are:

Celsius or Centigrade = °C
Fahrenheit = °F
Kelvin = °K

Common temperature measurements in each scale:

Degrees °C °F °K
Boiling Point of Water 100.00 212.00 373.00
Ice Point of Water 0.00 32.00 273.00
Absolute Zero -273.00 -460.00 0.00


 

The conversion of temperature readings from one scale to another can be easily calculated using the following formulas:

Degrees Celsius ➝ Degrees Fahrenheit Degrees Celsius x 1.8 + 32
Degrees Celsius ➝ Degrees Kelvin Degrees Celsius + 273.15
Degrees Fahrenheit ➝ Degrees Celsius (Degrees Fahrenheit) x 1.8
Degrees Fahrenheit ➝ Degrees Kelvin (Degrees Fahrenheit + 459.67) / 1.8
Degrees Kelvin ➝ Degrees Fahrenheit Degrees Kelvin x 1.8 - 459.67
Degrees Kelvin ➝ Degrees Celsius Degrees Kelvin - 273.15
