Key Features:

  1. Multiple Units: Convert between Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur.
  2. User-Friendly Interface: Simple and intuitive design for effortless conversions.
  3. Accurate Results: Based on standard temperature conversion formulas.

Understanding Temperature Scales

What is the formula of Celsius, Fahrenheit, Kelvin, Rankine, or Réaumur?

Each temperature scale has its unique formula for conversion:

  1. Celsius: \(°C\)
  2. Fahrenheit: \(°F = (°C × 9/5) + 32\)
  3. Kelvin: \(K = °C + 273.15\)
  4. Rankine: \(°R = (°C + 273.15) × 9/5\)
  5. Réaumur: \(°Ré = °C × 0.8\)

Differences between Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur scales

Each scale has its origin and use:

  1. Celsius: Widely used globally, based on the freezing and boiling points of water.
  2. Fahrenheit: Common in the US, based on the freezing point of brine and human body temperature.
  3. Kelvin: Used in scientific contexts, starts from absolute zero.
  4. Rankine: Used in engineering, also starts from absolute zero but uses Fahrenheit intervals.
  5. Réaumur: Less common, based on the freezing and boiling points of water but with a different interval.
