Where scales meet
Temperature measures the average kinetic energy of particles in a substance. Different scales were developed for different purposes.
Celsius: Based on water's freezing (0°) and boiling (100°) points. Fahrenheit: Water freezes at 32° and boils at 212°. Kelvin: Absolute scale starting at absolute zero. Used in science.

Common questions about temperature conversion
Multiply by 9/5 and add 32. Formula: °F = (°C × 9/5) + 32. Example: 20°C = 68°F.
0°C (freezing point of water) = 32°F.
Absolute zero is 0 K = -273.15°C = -459.67°F. It's the lowest possible temperature.
Water boils at 100°C = 212°F = 373.15 K at standard atmospheric pressure.
