Conversion Formulas
The exact mathematical relationships between temperature scales
°C → °F
F = (C × 9/5) + 32
0°C = 32°F
°F → °C
C = (F − 32) × 5/9
212°F = 100°C
°C → K
K = C + 273.15
0°C = 273.15 K
K → °C
C = K − 273.15
373.15 K = 100°C
°F → K
K = (F − 32) × 5/9 + 273.15
32°F = 273.15 K
K → °F
F = (K − 273.15) × 9/5 + 32
373.15 K = 212°F
