Temperature Conversion Formulas
Celsius to Fahrenheit: °F = (°C × 9/5) + 32. Fahrenheit to Celsius: °C = (°F − 32) × 5/9. Celsius to Kelvin: K = °C + 273.15.
Key Benchmark Temperatures
Water freezes at 0°C (32°F / 273.15K) and boils at 100°C (212°F / 373.15K). Normal human body temperature is ~37°C (98.6°F).
Scientific Applications in Kelvin
Kelvin is the SI unit of thermodynamic temperature where 0 K represents Absolute Zero, the cessation of all classical molecular motion.
