How to Convert Temperature
Temperature can be measured in three main scales: Celsius, Fahrenheit, and Kelvin. Each scale has different reference points and conversion formulas.
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
Temperature Scale Reference Points
Water Freezing Point: 0°C = 32°F = 273.15K
Water Boiling Point: 100°C = 212°F = 373.15K
Absolute Zero: -273.15°C = -459.67°F = 0K
Room Temperature: ~20°C = ~68°F = ~293.15K
Body Temperature: 37°C = 98.6°F = 310.15K
