Convert temperatures among Celsius, Fahrenheit, and Kelvin with standard thermodynamic offsets.
Formulas
- °C → °F:
F = C × 9/5 + 32 - °F → °C:
C = (F − 32) × 5/9 - Kelvin uses absolute zero offset:
K = °C + 273.15(and inverse)
Choose source and target scales; identical scales short-circuit to the input value.
When to use it
Cookbook temperature translation, lab report unit switches, weather data normalization, or teaching absolute versus relative temperature scales.
Limitations
Does not support Rankine or Réaumur. Results are real-number approximations — not rounded to significant figures for scientific publication unless you format manually. Negative Kelvin is physically meaningless and should not be entered.
