Enter Fahrenheit (°F) and Celsius (°C) to review celsius with this tool. The result expresses the same temperature in Celsius.
Converted value = Source value × Conversion factor
For affine conversions such as temperature, an offset is also applied.The calculation links Fahrenheit (°F) and Celsius (°C) to celsius. The result expresses the same temperature in Celsius. The relationship is C = (F − 32) × 5/9.
Enter Fahrenheit (°F) and Celsius (°C) to review celsius with this tool. The result expresses the same temperature in Celsius.
Read a Fahrenheit temperature in Celsius for a recipe, forecast or instrument.
The result expresses the same temperature in Celsius. The relationship is C = (F − 32) × 5/9.
Prepare Fahrenheit (°F) and Celsius (°C). Enter the Fahrenheit amount in the source field and read the Celsius output; retain extra digits until the final required rounding.
The result expresses the same temperature in Celsius. The relationship is C = (F − 32) × 5/9. Subtract 32 before applying the scale factor; temperature differences use a different conversion from absolute readings.
Use the full settings in the worked-example table. They produce celsius: 37.8. Compare the method and units as well as the displayed number.
The displayed relationship is C = (F − 32) × 5/9 Enter the Fahrenheit amount in the source field and read the Celsius output; retain extra digits until the final required rounding.
Subtract 32 before applying the scale factor; temperature differences use a different conversion from absolute readings. Check the original measurement, source data and the convention required by the task.
Worked fahrenheit to celsius converter example. Set Fahrenheit (°F) = 100; Celsius (°C) = 37.8. The corresponding output is celsius: 37.8. The result expresses the same temperature in Celsius.

| Field | Example value | Entry check |
|---|---|---|
| Fahrenheit (°F) | 100 | Read the source and destination units carefully; retain precision until the final rounding. |
| Celsius (°C) | 37.8 | Read the source and destination units carefully; retain precision until the final rounding. |
Relationship used for this example: C = (F − 32) × 5/9
The result expresses the same temperature in Celsius. The relationship is C = (F − 32) × 5/9.
| Output | Displayed result |
|---|---|
| celsius | 37.8 |
With these settings, celsius is 37.8. Use the same units and calculation mode when reproducing this example.
The result expresses the same temperature in Celsius. The relationship is C = (F − 32) × 5/9. Subtract 32 before applying the scale factor; temperature differences use a different conversion from absolute readings.
Replace the illustrative fahrenheit (°f) value (100) with your own value, then complete the other inputs for the same scenario. Enter the Fahrenheit amount in the source field and read the Celsius output; retain extra digits until the final required rounding.
