0 °C = 32 °F
Temperature Conversion Formulas
Celsius to Fahrenheit
°F = (°C × 9/5) + 32
Example: 20°C = (20 × 9/5) + 32 = 68°F
Fahrenheit to Celsius
°C = (°F - 32) × 5/9
Example: 68°F = (68 - 32) × 5/9 = 20°C
Celsius to Kelvin
K = °C + 273.15
Example: 20°C = 20 + 273.15 = 293.15K
Kelvin to Celsius
°C = K - 273.15
Example: 293.15K = 293.15 - 273.15 = 20°C
