Temperature measurement scales are based on different reference points:
- Celsius (°C): Calibrated around water (freezes at 0°C, boils at 100°C at standard pressure).
- Fahrenheit (°F): Freezes at 32°F and boils at 212°F.
- Kelvin (K): The thermodynamic absolute scale, where 0 K represents Absolute Zero (−273.15°C), the complete absence of thermal motion.
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 - Kelvin to Celsius:
°C = K − 273.15
