Convert between degrees Celsius (°C), degrees Fahrenheit (°F), and kelvin (K). Unlike linear units, temperature scales have different zero points, so conversions require offset formulas, not simple multiplication. Kelvin (K) is the SI base unit; 0 K is absolute zero (−273.15 °C).
This temperature converter transforms values from Kelvin (K) to Fahrenheit (°F). Temperature scales have different zero points, so conversion uses an offset formula, not a simple multiplier.
The kelvin (K) is the SI base unit of thermodynamic temperature; 0 K is absolute zero. Temperature intervals in K equal those in °C.
Degrees Fahrenheit (°F) is used primarily in the United States; 32 °F is the freezing point of water and 212 °F is its boiling point.
°F = (K × 9/5) − 459.67
°F = (K × 9/5) − 459.67
The conversion formula transforms K to °F. Values are first converted to kelvin (K), the SI base unit, then to the target scale, which avoids rounding errors from chained offset formulas. A change of 1 °C equals a change of 1 K, but 0 °C ≠ 0 K.
-441.67 °F = (10 K × 9/5) − 459.67 = -441.67 °F
