Rangdom

Convert a temperature into every scale at once

Enter one value and a unit — Celsius, Fahrenheit, Kelvin, or Rankine — and read it back in every scale at once. Temperature scales differ by offset, not just a factor: water freezes at 0 °C, 32 °F, 273.15 K, and 491.67 °R, so °F and °R do not share a zero with °C and K. Decimals and negative values are supported, but anything below absolute zero (−273.15 °C, i.e. 0 K) is rejected.
