    c °C to f °F: f = c × 1.8 + 32; f °F to k K: k = ⁠ f + 459.67 / 1.8 ⁠ k K to f °F: f = k × 1.8 − 459.67; There is also an exact conversion between Celsius and Fahrenheit scales making use of the correspondence −40 °F ≘ −40 °C. Again, f is the numeric value in degrees Fahrenheit, and c the numeric value in degrees Celsius:
