Conversion Formulas
Celsius ↔ Fahrenheit
°F = (°C × 9/5) + 32
°C = (°F - 32) × 5/9
Celsius ↔ Kelvin
K = °C + 273.15
°C = K - 273.15
Celsius ↔ Rankine
°R = (°C + 273.15) × 9/5
°C = (°R × 5/9) - 273.15
Fahrenheit ↔ Rankine
°R = °F + 459.67
°F = °R - 459.67

Temperature Unit Basics
Common Temperature Unit Definitions
Celsius (°C)
A temperature scale based on the freezing point (0°C) and boiling point (100°C) of water, part of the International System of Units, widely used in science and daily life.
Fahrenheit (°F)
A temperature scale primarily used in the United States and some former British colonies, with water freezing at 32°F and boiling at 212°F.
Kelvin (K)
The SI unit of thermodynamic temperature, where 0K represents absolute zero, used as the standard temperature unit in scientific research.
Rankine (°R)
A temperature scale based on absolute zero with the same degree intervals as Fahrenheit, commonly used in engineering fields.
Temperature Unit Application Scenarios
Scientific Research and International Exchange: Celsius and Kelvin are the temperature units commonly used in the international scientific community.
Daily Life: Most countries use Celsius to express weather and daily temperatures, while countries like the United States use Fahrenheit.
Industry and Engineering: Kelvin is very important in thermodynamic calculations, while Rankine is often used in certain engineering fields.
