Temperature Scales Explained
Celsius (°C)
- • Water freezes at 0°C
- • Water boils at 100°C
- • Used in most countries
- • Scientific standard
Fahrenheit (°F)
- • Water freezes at 32°F
- • Water boils at 212°F
- • Used in USA
- • Weather reports
Kelvin (K)
- • Absolute zero at 0K
- • Water freezes at 273.15K
- • Scientific measurements
- • No negative values
Pro Tip: For quick mental math, remember that Celsius to Fahrenheit is roughly doubling and adding 30. For example: 20°C × 2 + 30 ≈ 70°F (actual: 68°F).

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
