Introduction

Different scales are used to measure temperature around the world, with Celsius and Fahrenheit being the most common. A Temperature Conversion Calculator is a tool that helps in converting temperatures from one scale to another, ensuring consistency and understanding across different regions and disciplines.

Understanding Different Scales

Celsius (°C): This scale was developed by Anders Celsius in 1742. It sets the freezing point of water at 0°C and the boiling point at 100°C under standard atmospheric pressure. The scale is based on 100 equal parts between the freezing and boiling points of water.

Fahrenheit (°F): Developed by Daniel Gabriel Fahrenheit in 1724, this scale sets the freezing point of water at 32°F and the boiling point at 212°F under standard atmospheric pressure. The scale is divided into 180 equal parts between these two points.

Newton (°N): Sir Isaac Newton's scale was an early attempt to measure temperature, but it is not commonly used today. It is based on the freezing and boiling points of water, similar to Celsius, but with a different zero point.

Delisle (°D): The Delisle scale, developed by Joseph-Nicolas Delisle in 1738, is a reverse scale where the boiling point of water is 0°D and the freezing point is 150°D.

Kelvin (K): The Kelvin scale, part of the International System of Units (SI), is an absolute temperature scale where 0 K is absolute zero, the theoretical point at which all molecular motion stops. It is used in scientific research and high-precision applications.

Réaumur (°Ré): Developed by René Antoine Ferchault de Réaumur in 1730, the Réaumur scale was widely used in France and its colonies. It sets the freezing point of water at 0°Ré and the boiling point at 80°Ré.

Rankine (°R): The Rankine scale, named after William John Macquorn Rankine, is an absolute temperature scale used primarily in engineering, particularly in the field of thermodynamics. It is equivalent to the Fahrenheit scale but with absolute zero as 0°R.

Romer (°Rø): Developed by Ole Rømer in 1701, the Romer scale was one of the first temperature scales to define boiling point and freezing points of water.
