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.
