About Temperature Conversion

Temperature is a measure of how hot or cold something is. The three main temperature scales are Celsius (used worldwide), Fahrenheit (used in the US), and Kelvin (used in science).

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

Key Reference Points

Water freezes: 0°C = 32°F = 273.15K
Water boils: 100°C = 212°F = 373.15K
Body temperature: 37°C = 98.6°F = 310.15K
Room temperature: 20-22°C = 68-72°F
Absolute zero: -273.15°C = -459.67°F = 0K

Quick Mental Math Tips

To roughly convert °C to °F: Double and add 30
To roughly convert °F to °C: Subtract 30 and halve
16°C ≈ 61°F (digits reversed!)
28°C ≈ 82°F (digits reversed!)
