Exact conversion relationship
The Celsius and Fahrenheit scales have different zero points and step sizes. Multiply Celsius by 9/5, then add 32.
Where this conversion is useful
Celsius-to-Fahrenheit conversion is useful for weather forecasts, cooking temperatures, healthcare, travel and scientific communication between metric and US customary settings.
Understanding the result
Water freezes at 0 °C or 32 °F and boils at 100 °C or 212 °F at standard atmospheric pressure. The two scales meet at −40 degrees.
Weather, body and cooking temperatures
Context matters: body temperature uses a narrow medical range, while ovens and weather span much wider values. A numerical conversion does not replace medical or food-safety guidance.
Precision and rounding
The calculator keeps full numerical precision internally and rounds only the displayed values. Match the displayed precision to the accuracy of your original measurement.
Zero is accepted and converts correctly.
Batch conversion for lists and records
Paste a short list to create a clean two-column result table for specifications, logs, planning notes or comparisons.

Celsius to Fahrenheit Converter – Frequently asked questions
How do I convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 and add 32.
What is 20 degrees Celsius in Fahrenheit?
Twenty degrees Celsius equals 68 degrees Fahrenheit.
At what temperature are Celsius and Fahrenheit equal?
The two scales show the same numerical value at −40 degrees.
What is normal body temperature in Fahrenheit?
A commonly cited reference of 37 °C equals 98.6 °F, but normal ranges vary.
Can I enter a negative temperature?
Yes. Negative temperatures are valid and are converted normally.
Why is this not a simple multiplication?
Celsius and Fahrenheit have different zero points, so the formula needs both multiplication and an offset.
Can I convert a list of temperatures?
Yes. The batch tool accepts up to 50 values.
