Quick Answer & Understanding Your Result
A Temperature Converter translates thermal scales between Celsius (°C), Fahrenheit (°F), and absolute thermodynamic Kelvin (K) using standard SI temperature conversion equations.
The 3 Core Temperature Scales
- Celsius (°C): Defined with 0^circ C as the freezing point of water and 100^circ C as the boiling point at 1 atm.
- Fahrenheit (°F): Standard Imperial scale used primarily in the United States (32^circ F freezing, 212^circ F boiling).
- Kelvin (K): Absolute SI thermodynamic temperature scale (0 K = -273.15^circ C absolute zero).
Key Mathematical Conversion Formulas
- Celsius to Fahrenheit: ^circ F = (^circ C × 9/5) + 32.
- Fahrenheit to Celsius: ^circ C = (^circ F - 32) × 5/9.
- Celsius to Kelvin: K = ^circ C + 273.15.
