How to convert celsius to kelvin
Temperature scales use offset formulas, not a simple multiplier.
`°F = °C × 9/5 + 32` · `K = °C + 273.15` · `°R = (°C + 273.15) × 9/5`.
1 °C ≈ 274.15 K

Temperature conversion — common questions
What is 100°F in Celsius?
100°F = (100 − 32) × 5/9 = 37.78°C — close to human body temperature.
Is 0 K really the coldest possible temperature?
Yes. 0 Kelvin is absolute zero (−273.15°C), the theoretical lowest temperature where all classical motion stops.
Why is the Fahrenheit-to-Celsius formula not just a multiplication?
Because the zero points differ: 0°C corresponds to 32°F, so an offset of 32 is required in addition to the 5/9 scale factor.
