How to convert degrees Celsius to degrees Fahrenheit
Temperature conversions need more than a multiplier because Celsius, Fahrenheit, and Kelvin have different zero points.

Start with your value in degrees Celsius, then apply the formula below. It stays visible so you can catch rounding mistakes instead of just copying the output.

Formula
°F = (°C × 9/5) + 32

Use the converted temperature for weather, cooking, lab notes, thermostats, and thermal references, but remember that context such as pressure can affect boiling and freezing points.

The formula stays visible because multiplying by a factor alone is not enough when the scale has a shifted zero point. This page displays converted values with up to 2 decimal places by default.

FAQs
These answers use the same formula as the converter above.
How do I convert degrees Celsius to degrees Fahrenheit?

Enter the value in degrees Celsius and apply °F = (°C × 9/5) + 32. Round the degrees Fahrenheit result after the conversion, not before.

What is 1 degree Celsius in degrees Fahrenheit?

1 °C equals 33.8 °F with the current rounding setting. Keep more decimal places when the result feeds another calculation.

What is -40 °C in °F?

-40 °C is -40 °F. It appears in the lookup table so you can compare it with nearby amounts.

Can I convert degrees Fahrenheit back to degrees Celsius?

Yes. Use the reverse Degrees Fahrenheit to Degrees Celsius converter if you need to go the other direction.

How accurate is this degrees Celsius to degrees Fahrenheit conversion?

The calculator runs the formula in your browser and rounds results to 2 decimal places by default. The formula stays visible because multiplying by a factor alone is not enough when the scale has a shifted zero point.
