Temperature Converter
Fast and accurate temperature converter between Celsius (°C), Fahrenheit (°F), Kelvin (K), and UK Gas Mark ratings. Perfect for cooking recipes, convection baking, and scientific calculations.
Oven Temperature & Gas Mark Converter
Convert between Celsius (°C), Fahrenheit (°F), UK Gas Marks, and fan-assisted convection settings
Convection ovens circulate hot air more efficiently: reduce recommended recipe temperature by 20°C (approx 25°F-50°F).

How to use
- Adjust the temperature slider in Celsius or Fahrenheit.
- View instant conversions into Fahrenheit, Celsius, and Kelvin.
- Toggle fan-assisted convection mode to see automatically adjusted lower baking temperatures (-20°C / -25°F).
- Check corresponding UK Gas Mark presets (from 1/4 to 10).
- Review the culinary baking temperature reference cheat sheet.
Temperature conversion formulas
Celsius to Fahrenheit: °F = °C × 9/5 + 32.
Fahrenheit to Celsius: °C = (°F − 32) × 5/9.
Celsius to Kelvin: K = °C + 273.15.
Convection fan-assisted adjustments
Convection fans circulate heated air continuously, significantly boosting radiant heat transfer.
Standard culinary practice calls for reducing target oven temperatures by 20°C (approx 25°F to 50°F) when baking with forced fan convection.
Understanding UK Gas Marks
Historic gas ovens regulate temperature by Gas Mark numbers: Mark 1/4 (110°C / 225°F) for meringue drying, Mark 4 (180°C / 350°F) for general roasting and cakes, and Mark 9 (240°C / 475°F) for high-heat pizza searing.
Frequently Asked Questions
What is 350°F in Celsius?
350°F corresponds to approximately 177°C (standardly rounded to 180°C in culinary recipes).
How do you convert fan oven recipes?
Reduce the conventional temperature by 20°C (e.g. 200°C conventional becomes 180°C fan-assisted).
What is Gas Mark 4 in degrees?
Gas Mark 4 equals 180°C or 350°F, the benchmark temperature for most sweet bakes.
What is absolute zero?
Absolute zero is 0 Kelvin or −273.15°C (−459.67°F), the lowest theoretical thermodynamic limit.
