Origins of the Temperature
What is Celsius ?
The Celsius temperature scale is widely used globally and was developed by Swedish astronomer and physicist Anders Celsius in the 18th century. Celsius initially proposed a scale with 0 degrees as the boiling point of water and 100 degrees as the freezing point of water, which was later reversed to its current form with 0 degrees as the freezing point and 100 degrees as the boiling point of water.
The simplicity and reference points based on the properties of water made the Celsius scale widely adopted and essential for scientific and everyday temperature measurements. It is also known as the centigrade scale
What is Fahrenheit ?
The Fahrenheit scale was developed by Polish-German physicist and engineer Daniel Gabriel Fahrenheit in 1724. Fahrenheit used a specific mixture of ice and salt to define zero degrees on the scale and the average human body temperature to define 100 degrees.
What is Kelvin ?
The Kelvin scale, also known as the absolute temperature scale, was proposed by William Thomson, known as Lord Kelvin, based on the concept of absolute zero, where molecular motion stops. Lord Kelvin collaborated with other physicists to refine the Kelvin temperature scale , which provides a universal reference point for measuring temperature independent of the properties of any specific material
What is Rankine ?
The Rankine scale was developed in the 19th century by Scottish physicist and engineer William John Macquorn Rankine. It is related to the Kelvin scale, where the Kelvin degree is the same size as the Rankine degree. The Rankine scale begins at absolute zero, so 0 °R is the same as -459.67°F. It is still used in some engineering calculations involving thermodynamic processes, especially in fields related to heat transfer, fluid dynamics, and energy systems
