Temperature isn't a simple linear scale; Celsius and Fahrenheit have different zero points, and absolute scales (Kelvin, Rankine) start at absolute zero. Temperature Converter applies the exact conversion formulas: °F = °C × 9/5 + 32, K = °C + 273.15, °R = K × 9/5. We warn if you go below absolute zero, since that's physically impossible. The table at the bottom shows your value on all four scales at once. Runs entirely in your browser.
