## Prompt

Convert 72F to Celsius, to the nearest degree.

## Response

72°F is approximately **22°C** when converted to Celsius and rounded to the nearest degree.

Using the standard formula for temperature conversion:
\[
^\circ C = (^\circ F - 32) \times \frac{5}{9}
\]

Substitute 72°F:
\[
^\circ C = (72 - 32) \times \frac{5}{9} = 40 \times \frac{5}{9} = \frac{200}{9} \approx 22.22^\circ C
\]
Multiple calculators and conversion tables confirm that **72°F = 22.22°C**, which rounds to **22°C**.[CK-12](https://www.ck12.org/flexi/physical-science/temperature-in-physics/convert-72-degrees-fahrenheit-to-celsius./)[Inch Calculator](https://www.inchcalculator.com/convert/fahrenheit-to-celsius/?degrees=72)[UnitCompare](https://unitcompare.com/fahrenheit-to-celsius/72)
