72 degrees Fahrenheit converts to 22.2222 degrees Celsius.
To convert 72°F to Celsius, we apply the formula that takes the Fahrenheit temperature, subtracts 32, then multiplies by 5/9. This gives the equivalent temperature on the Celsius scale, which measures temperature differently than Fahrenheit.

Conversion Formula
The formula to convert Fahrenheit (°F) to Celsius (°C) is:
Celsius = (Fahrenheit – 32) × 5/9
This formula works because the Fahrenheit and Celsius scales are offset and scaled differently. Fahrenheit sets the freezing point of water at 32°F, while Celsius sets it at 0°C. The ratio between the two scales is 5 to 9, so we subtract 32 to adjust for the offset, then multiply by 5/9 to convert the size of the degree.
For example, converting 72°F:
- Subtract 32: 72 – 32 = 40
- Multiply by 5/9: 40 × 5/9 = 200/9 ≈ 22.2222
- Result: 22.2222°C
Conversion Example
- Convert 50°F to Celsius:
- 50 – 32 = 18
- 18 × 5/9 = 10
- Result: 10°C
- Convert 85°F to Celsius:
- 85 – 32 = 53
- 53 × 5/9 ≈ 29.4444
- Result: 29.4444°C
- Convert 60°F to Celsius:
- 60 – 32 = 28
- 28 × 5/9 ≈ 15.5556
- Result: 15.5556°C
- Convert 90°F to Celsius:
- 90 – 32 = 58
- 58 × 5/9 ≈ 32.2222
- Result: 32.2222°C

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric pressure. It is mostly used in the United States, its degree intervals represent smaller increments compared to Celsius, making it sometimes less intuitive for scientific purposes.
Celsius: Celsius is a temperature scale based on the freezing point of water at 0 degrees and boiling at 100 degrees, used worldwide for scientific and daily temperature measurement. The scale divides the temperature range into 100 equal parts, making it straightforward to work with in metric system contexts.
Conversion FAQs
Why do we subtract 32 in the Fahrenheit to Celsius formula?
The number 32 accounts for the offset in the Fahrenheit scale where water freezes. Since the Celsius scale sets freezing at 0 degrees, subtracting 32 removes this offset, allowing the temperature difference to be scaled correctly when multiplied by 5/9.
Can the conversion formula be reversed to convert Celsius to Fahrenheit?
Yes, to convert Celsius back to Fahrenheit, you multiply the Celsius temperature by 9/5 and then add 32. This reverses the subtraction and scaling done in the Fahrenheit to Celsius conversion, ensuring accurate temperature translation both ways.
Why is the multiplication factor 5/9 used in the formula?
The 5/9 factor reflects the ratio of the size of one Celsius degree to one Fahrenheit degree. Since 180 Fahrenheit degrees (from freezing to boiling) equals 100 Celsius degrees, the ratio 5/9 scales the temperature difference properly for conversion.
Is the conversion precise if I round to fewer decimal places?
Rounding to fewer decimals reduces precision but usually remains sufficient for everyday use. Scientific calculations require more decimals to maintain accuracy, while casual temperature readings can often round to one or two decimals without causing issues.
Does this conversion formula work for negative Fahrenheit values?
Yes, the formula applies to all Fahrenheit values, including negatives. The subtraction and multiplication steps remain the same, accurately converting cold temperatures below freezing into Celsius scale.
