Convert between Celsius (°C), Fahrenheit (°F), and Kelvin (K)
°C to °F:
°F = (°C × 9/5) + 32
°F to °C:
°C = (°F − 32) × 5/9
°C to K:
K = °C + 273.15
K to °C:
°C = K − 273.15
°F to K:
K = (°F − 32) × 5/9 + 273.15
K to °F:
°F = (K − 273.15) × 9/5 + 32
Description | °C | °F | K |
---|---|---|---|
Absolute Zero | -273.15 | -459.67 | 0 |
Freezing Point of Water | 0 | 32 | 273.15 |
Room Temperature | 20-25 | 68-77 | 293.15-298.15 |
Average Human Body | 37 | 98.6 | 310.15 |
Boiling Point of Water | 100 | 212 | 373.15 |
