I am often asked for a conversion chart from British gas mark temps to Celsius or Fahrenheit. Here's a table that I got from the web a long time ago - I didn't 'save' the website addy, so unable to give a 'credit' here!
Heat Level in Degrees Fahrenheit/Degrees Celsius /British (Regulo) Gas Mark
Very cool 200/ 95/ 0 Very cool 225/110 /1/4 (quarter) Very cool 250/120/1/2 (half) Cool or slow 275/135/1 Cool or slow 300/150/2 Warm 325/165/3 Moderate 350/175/4 Moderately hot 375/190/5 Fairly hot 400/200/6 Hot 425/220/7 Very Hot 450/230/8 Very Hot 475/245/9
