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

Temperature Conversion FAQ
What's the difference between Celsius and Kelvin?
Kelvin is an absolute temperature scale starting at absolute zero (-273.15°C). To convert: K = °C + 273.15. Kelvin is used in scientific calculations where absolute temperature is required.
Why does -40°C equal -40°F?
This is the point where the Celsius and Fahrenheit scales intersect. The formula (°C × 9/5) + 32 = °F gives the same result when both °C and °F equal -40.
What is the Rankine temperature scale?
Rankine is an absolute temperature scale that uses Fahrenheit-sized degrees but starts at absolute zero (0°R = -459.67°F). It's primarily used in engineering applications in the United States.
