Conversion Formulas
Converting TO Celsius (°C)
From Fahrenheit: °C = (°F - 32) × 5/9
From Kelvin: °C = K - 273.15
From Rankine: °C = (°R - 491.67) × 5/9
Converting FROM Celsius (°C)
To Fahrenheit: °F = (°C × 9/5) + 32
To Kelvin: K = °C + 273.15
To Rankine: °R = (°C × 9/5) + 491.67
Direct Conversions
F to K: K = (°F - 32) × 5/9 + 273.15
K to F: °F = (K - 273.15) × 9/5 + 32
K to R: °R = K × 9/5
R to K: K = °R × 5/9

Temperature Scales
Celsius (°C): Based on water's freezing (0°) and boiling (100°) points at standard pressure
Fahrenheit (°F): Water freezes at 32° and boils at 212°. Commonly used in the United States
Kelvin (K): Absolute temperature scale starting from absolute zero (-273.15°C)
Rankine (°R): Absolute scale like Kelvin but using Fahrenheit-sized degrees
