How to convert degrees Fahrenheit to degrees Celsius

Temperature scales start from different zero points, so the conversion is not a single multiplication. Use the formula above: °C = (°F − 32) × 5/9. For example, 20 f is -6.666667 c.

Quick estimate

Work through the formula above for exact results; for weather temperatures, “double and add 30” (°C to °F) or “take 30 and halve” (°F to °C) gets within a few degrees.

Questions

How many degrees Celsius are in a degree Fahrenheit?

This is a temperature scale, so it depends on the value: use °C = (°F − 32) × 5/9.

How do I convert degrees Fahrenheit to degrees Celsius in a spreadsheet?

Put the temperature in A1 and type =(A1-32)*5/9.

Are the values in the table exact?

They are calculated from the exact definitions of the units and rounded only for display. Open any row for the full working.
