Applications

Weather

85°F = 29.4°C. Understanding US weather forecasts when travelling.

Cooking

350°F oven = 176.7°C. Convert US recipes for Australian ovens.

Science

98.6°F (body temp) = 37°C. Medical measurements use both scales.

Converting Temperature for Cooking

Our temperature converter is particularly useful when cooking, as it allows you to easily convert temperatures between Fahrenheit and Celsius. For example, if a recipe calls for 350°F (175°C), but your oven only goes up to 400°F (200°C), our converter can help you determine the equivalent temperature in Celsius.

Frequently Asked Questions

How do you convert °F to °C?

Subtract 32, then multiply by 5/9. (100°F − 32) × 5/9 = 37.8°C.

What is 72°F in °C?

(72 − 32) × 5/9 = 22.2°C (comfortable room temperature).

What is the easiest way to estimate?

Subtract 30 and divide by 2. 80°F → (80−30)/2 = 25°C (actual 26.7°C).

Can I convert temperatures that are not whole numbers?

Yes, our converter can handle decimal temperatures as well.

How do I convert a temperature range to Celsius?

Simply enter the lower and upper temperatures in Fahrenheit and our converter will give you the corresponding range in Celsius.
