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
Fahrenheit to Kelvin: K = (°F - 32) × 5/9 + 273.15
Kelvin to Fahrenheit: °F = (K - 273.15) × 9/5 + 32
Common Temperature Conversions
0°C = 32°F = 273.15K (water freezing), 25°C = 77°F = 298.15K (room temperature), 37°C = 98.6°F = 310.15K (body temperature), 100°C = 212°F = 373.15K (water boiling)
