140
Conversion: 275°F → (275 - 32) × 5/9 °C =135°C For cooking purposes 275°F (gas mark 1) is converted at 140°C
That completely depends on the temperature of the water when the gas flame is first ignited, which you've neglected to mention.
11% of 140= 11% * 140= 0.11 * 140= 15.4
120% of 140= 120% * 140= 1.2 * 140= 168
To convert gas mark to electric oven temperature, you can use the following approximate conversions: Gas Mark 1 is about 275°F (140°C), Gas Mark 4 is about 350°F (180°C), and Gas Mark 6 is about 400°F (200°C). Keep in mind that electric ovens may vary, so it's always best to refer to your oven manual for specific temperature settings.
170 degrees Celsius is equivalent to gas mark 3.
Gas mark 4.
140
gas mark 4
The equivalent gas mark would be 4, although all ovens vary so check the documentation that came with your own to be certain.
