GoTo (goto, GOTO, GO TO or other case combinations, depending on the programming language) is a statement found in many computer programming languages.It performs a one-way transfer of control to another line of code; in contrast a function call normally returns control. The jumped-to locations are usually identified using labels, though some languages use line numbers.

The equation to convert between Kelvin and Celsius is: °C = K – 273.15; Celsius temperature have a degree symbol while those reported in Kelvin do not. While the size of the degree is the same between Kelvin and Celsius, there is no point at which the two scales are equal. A Celsius temperature will always be higher than Kelvin.

Kelvin to Celsius formula. Kelvin (K) to Celsius (°C) temperature conversion. Kelvin to Celsius conversion formula. The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:. T (°C) = T (K) – 273.15. Example. Convert 300 Kelvin to degrees Celsius: T (°C) = 300K – 273.15 = 26.85 °C. Try: Kelvin to Celsius converter Kelvin to Celsius conversion table
