Temperature Unit Converter

Celsius, Fahrenheit, and Kelvin cover almost every everyday and scientific context, but Rankine still shows up specifically in certain US engineering and thermodynamics calculations, an absolute temperature scale like Kelvin, starting at true zero, but sized in Fahrenheit-scale degrees rather than Celsius-scale ones, which makes it a genuinely different animal from the other three rather than just another everyday unit. This tool converts between all four, Celsius, Fahrenheit, Kelvin, and Rankine, covering the rare scale most everyday converters skip entirely alongside the three that come up constantly. Useful for a thermodynamics or aerospace engineering calculation that specifically works in Rankine, converting a Rankine value from a textbook or a technical spec into a more familiar scale, or handling the full range of four scales in one place instead of needing a separate reference for the one scale most tools leave out.
