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.
