How this Fahrenheit to Centigrade calculator works
This calculator uses the standard formula for converting Fahrenheit to Centigrade (also called Celsius): (°F − 32) × 5/9 = °C. Simply type a Fahrenheit value, click the button, and the converted Centigrade value is shown instantly.
The tool accepts whole numbers and decimals, so it works for weather temperatures, cooking, science homework, and medical readings. It also supports quick example buttons if you want to test common reference points.
Fahrenheit to Centigrade formula
Conversion equation
The Fahrenheit and Centigrade scales have different zero points and different degree sizes. To convert accurately, you must first shift by 32 degrees and then scale by 5/9:
- Step 1: Subtract 32 from the Fahrenheit temperature.
- Step 2: Multiply the result by 5.
- Step 3: Divide that value by 9.
Manual example
Convert 95°F to Centigrade:
- 95 − 32 = 63
- 63 × 5 = 315
- 315 ÷ 9 = 35
So, 95°F = 35°C.

Quick accuracy tips
If you need rough mental math, subtract 30 and divide by 2. This approximation is quick but not exact. For reliable results in anything important—especially medical or scientific contexts—use the exact formula in the calculator above.
Frequently asked questions
Is centigrade the same as Celsius?
In everyday use, yes. “Centigrade” is the older name; “Celsius” is the modern standard term.
Can temperatures below 32°F convert to negative Centigrade values?
Yes. Any Fahrenheit value below the freezing point of water (32°F) converts to a negative Celsius number. For example, 14°F is about -10°C.
Does this calculator round values?
Yes. Results are shown cleanly with up to two decimal places while preserving accuracy for practical use.
