Temperature Conversion Formulas

The converter uses standard temperature conversion formulas:

From Celsius:

°F = (°C × 9/5) + 32
K = °C + 273.15
°R = (°C + 273.15) × 9/5
°r = °C × 4/5

From Fahrenheit:

°C = (°F - 32) × 5/9
K = (°F + 459.67) × 5/9
°R = °F + 459.67
°r = (°F - 32) × 4/9

From Kelvin:

°C = K - 273.15
°F = (K × 9/5) - 459.67
°R = K × 9/5
°r = (K - 273.15) × 4/5

From Rankine:

°C = (°R - 491.67) × 5/9
°F = °R - 459.67
K = °R × 5/9
°r = (°R - 491.67) × 4/9

From Reaumur:

°C = °r × 5/4
°F = (°r × 9/4) + 32
K = (°r × 5/4) + 273.15
°R = (°r × 9/4) + 491.67

Temperature Scales Explained

Celsius (°C): The Celsius scale is used in most of the world for temperature measurement, with 0°C being the freezing point of water and 100°C the boiling point at sea level.

Fahrenheit (°F): Primarily used in the United States, the Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F.

Kelvin (K): The Kelvin scale is the base unit of temperature in the International System of Units (SI), used in scientific work. Absolute zero (0K) is the lowest possible temperature.

Rankine (°R): The Rankine scale is an absolute temperature scale based on Fahrenheit degrees, used in some engineering systems.

Reaumur (°r): A historical temperature scale where the freezing and boiling points of water are set to 0°r and 80°r respectively.
