About this calculator
The gas mark scale is a British system for oven temperatures, historically tied to the pressure setting on gas ovens, running roughly from a low gas mark ¼ (about 225°F/107°C) up through gas mark 9 (about 475°F/246°C) in fixed steps. This converter translates a gas mark into its Fahrenheit equivalent (and back), along with the matching Celsius reading, since gas mark, Fahrenheit, and Celsius are the three temperature systems that appear interchangeably across older and modern British recipes.
It's a practical kitchen reference for home cooks following British or Commonwealth recipes on an oven dialed in Fahrenheit or Celsius, since many classic UK cookbooks — and plenty of newer ones — still list oven heat purely as a gas mark number without a numeric temperature alongside it.
