🌡️ Temperature Conversion
🧪 Quick Examples
📚 Temperature Scales
Celsius (°C)
Based on the freezing (0°C) and boiling (100°C) points of water at sea level.
Origin: Developed by Anders Celsius in 1742
Usage: Used worldwide, especially in science and most countries
Fahrenheit (°F)
Based on a mixture of ice, water, and salt (0°F) and human body temperature (96°F, later 98.6°F).
Origin: Developed by Daniel Gabriel Fahrenheit in 1724
Usage: Primarily used in the United States
Kelvin (K)
Absolute temperature scale starting from absolute zero, where all molecular motion stops.
Origin: Developed by William Thomson (Lord Kelvin) in 1848
Usage: Used in scientific applications and physics

🧮 Conversion Formulas
Celsius ↔ Fahrenheit
°F = (°C × 9/5) + 32
°C = (°F - 32) × 5/9
Celsius ↔ Kelvin
K = °C + 273.15
°C = K - 273.15
Fahrenheit ↔ Kelvin
K = (°F - 32) × 5/9 + 273.15
°F = (K - 273.15) × 9/5 + 32
