About the Temperature Converter

Supported temperature systems:

Kelvin (K): SI base unit of temperature; 0 K is absolute zero (about −273.15°C)
Celsius (°C): most common; 0°C is water's freezing point, 100°C is boiling point
Fahrenheit (°F): mainly used in the US; 32°F freezing, 212°F boiling
Rankine (°R): 0°R is absolute zero; used in engineering thermodynamics
Réaumur (°Ré): 0°Ré freezing, 80°Ré boiling

Conversion formulas:

K = °C + 273.15
°F = °C × 9/5 + 32
°R = (°C + 273.15) × 9/5
°Ré = °C × 0.8

Note: All conversions follow international standards and are formatted to 4 decimal places.

Conversion Tips

• When converting between number systems, pay attention to the base of the original value to avoid input errors
• In binary conversion, every four binary digits directly correspond to one hexadecimal digit
• For decimal to binary conversion, use the division by 2 method and read the remainders from bottom to top
• Scientific notation can simplify the representation of very large or very small numbers
