Celsius to Fahrenheit formula
This converter changes Celsius to Fahrenheit using the formula F = C * 9 / 5 + 32. For example, 1 degree Celsius equals 33.8 degrees Fahrenheit, 5 degrees Celsius equals 41 degrees Fahrenheit, and 10 degrees Celsius equals 50 degrees Fahrenheit. Temperature conversions are based on the Kelvin scale.
Formula model
F = C * 9 / 5 + 32
1 Celsius equals
Quick factor: 1 deg C = 33.8 deg F.
To quickly estimate, double the Celsius value and add 30 for a rough Fahrenheit equivalent.
Use the exact formula for precise conversions, especially in scientific or cooking contexts.
Temperature conversions can include both a scale and an offset, so a multiplication factor alone is not always sufficient.
Precision and rounding
The calculation uses the catalog's fixed scale and offset definitions between deg C and deg F. Full decimal precision is kept for the calculation; only the displayed value is rounded for readability.

FAQ
Celsius to Fahrenheit questions
Why is 0 degrees Celsius equal to 32 degrees Fahrenheit?
The formula F = C * 9 / 5 + 32 gives 32 when C is 0, because the Fahrenheit scale sets its zero point at a different reference than Celsius.
What is the conversion for 100 degrees Celsius?
Using the formula, 100 degrees Celsius equals 212 degrees Fahrenheit, which is the boiling point of water at standard pressure.
