Gas Marks

Gas marks are an industrial measure used on stoves, ovens, grills and other related devices to estimate a temperature scale. Typically, the scale is used on devices in Great Britain, Ireland and some Commonwealth of Nations countries. It is closely related to similar scales, such as Stufe and Thermostat, used in other countries. The gas marks, also known as Regulo marks, refer to the regularly spaced physical marks placed on a control dial used to regulate gas flow.
