Temperature conversion notes
- Kelvin and Rankine use absolute zero as their origin; negative values are not physically meaningful for ideal gases.
- Delisle and Rømer scales invert or offset boiling/freezing points, so large numbers may trend opposite to Celsius.
- Calculations assume linear relationships; results are formatted with up to six decimal places for clarity.
