What is Gas Mark?
Gas Mark is a UK oven temperature scale, mainly used on gas ovens and in older recipes, running from around 1/4 up to 9.
What if my temperature doesn't land exactly on a Gas Mark?
It shows the nearest published Gas Mark and labels it as an estimate. Oven dials aren't perfectly linear, so treat it as a close match rather than exact.
