Temperature Scales Explained
Celsius (°C)
The most widely used temperature scale where water freezes at 0°C and boils at 100°C. Developed by Swedish astronomer Anders Celsius in 1742.
Fahrenheit (°F)
Primarily used in the United States, with water freezing at 32°F and boiling at 212°F. Created by German physicist Daniel Gabriel Fahrenheit in 1724.
Kelvin (K)
The SI base unit for temperature where absolute zero is 0K. Proposed by British physicist William Thomson (Lord Kelvin) in 1848.
