Temperature Conversion Charts & Tools: °F to °C, Kelvin, Oven Marks
Accurate and easy-to-use temperature conversion guides. Convert Celsius to Fahrenheit instantly, including common oven and food benchmarks. All conversions in one place.
In a global culinary world, you'll find recipes using Fahrenheit (American), Celsius (European, Australian, Canadian), and Kelvin (scientific). Converting between them is a two-step formula — but having a ready reference chart is faster.
The Three Temperature Scales
- Fahrenheit (°F): Used primarily in the United States. Water freezes at 32°F and boils at 212°F.
- Celsius (°C): International standard used in cooking guides, scientific work, and every country outside the US. Water freezes at 0°C and boils at 100°C.
- Kelvin (K): Scientific absolute scale. 0 K = absolute zero (-459.67°F / -273.15°C). Used in physics, chemistry, and engineering.
Common Cooking Temperature Conversions

| Safe fridge maximum | 40°F | 4°C | — |
| Slow oven | 275°F | 135°C | Gas Mark 1 |
| Moderate baking | 325–350°F | 163–177°C | Gas Mark 3–4 |
| Standard baking | 375°F | 190°C | Gas Mark 5 |
| Hot baking / roasting | 400°F | 204°C | Gas Mark 6 |
| High-heat roasting | 425–450°F | 218–232°C | Gas Mark 7–8 |
| Broiling / pizza | 500–550°F | 260–288°C | Gas Mark 9–10 |
| Safe poultry (internal) | 165°F | 74°C | — |
| Water boiling (sea level) | 212°F | 100°C | — |

Salt Water Freezing Point: 28°F vs. 32°F for Pure Water
Salt water freezes at about 28°F (-2°C) — lower than pure water's 32°F (0°C). See freezing points by salt concentration, why roads are salted, and how pressure and altitude change the freeze point.
