ABOUT THIS CONVERSION
Convert degrees Celsius to degrees Fahrenheit
Celsius and Fahrenheit have different zero points and degree sizes. The converter multiplies Celsius by 9/5 and then adds 32; it cannot use a simple factor through zero as length or mass conversions do.
Real-world example
A temperature of 20 °C is 68 °F, a typical mild indoor or outdoor temperature. Weather stations and thermostats may round to whole degrees, so their displayed reverse conversion may differ slightly.
Rounding and precision
Weather and room temperatures usually need no more than one decimal place. Laboratory work should follow instrument uncertainty. Preserve the offset calculation before rounding; rounding the intermediate Celsius or kelvin value can shift the final answer.
Regional context
Most countries report everyday temperature in Celsius, while the United States commonly uses Fahrenheit. Scientific standards use kelvin without the degree sign. Recipe temperatures must be checked for both scale and oven behavior.
Common mistake
Do not only multiply by 1.8; the 32-degree offset is essential. Also remember that a change of 1 °C equals a change of 1.8 °F even though the absolute readings need the offset.

USEFUL ANSWERS
°C to °F FAQs
At what temperature are Celsius and Fahrenheit equal?
They have the same numerical value at −40 degrees.
Why does 0 °C become 32 °F?
The scales use different reference points: water freezes at 0 °C and 32 °F under standard conditions.
How do I convert degrees Celsius to degrees Fahrenheit?
Enter the °C value in the calculator. It applies the scale offsets shown in the formula and returns the equivalent in °F; the formula and common-value table are shown on this page.
Is the °C to °F conversion exact?
Defined measurement relationships are calculated with decimal arithmetic from stored standards. The displayed answer may be rounded for readability. Currency results instead depend on the dated reference rate shown.
FROM UNIT
Celsius
Degrees Celsius use the same interval as kelvin, with 0 °C equal to 273.15 K. Its stored scale and offset express readings as kelvin before conversion.

Fahrenheit
The Fahrenheit scale places water's freezing point at 32 °F and boiling point near 212 °F at standard pressure. Its stored scale and offset express readings as kelvin before conversion.
