72°F to Celsius
72°F = 22.2°C = 295.37 K
Working: (72 − 32) × 5/9 = 22.2
72 degrees Fahrenheit converts to 22.2 degrees Celsius.
To convert Fahrenheit to Celsius, subtract 32 first, then multiply by 5/9. For 72°F: 72 − 32 = 40, and 40 × 5/9 = 22.2. The subtraction comes first because the two scales have different zero points — water freezes at 0°C but at 32°F.
A quick mental estimate is to subtract 30 and halve the result, which gives about 21°C — 1.2 degrees off the exact 22.2°C. That is close enough to judge the weather, though it drifts badly at oven temperatures.
Seventy-two is the default American thermostat setting and the temperature most often meant by 'comfortable' in US building guidance. It comes to 22.2°C, an untidy figure in metric — which is why European thermostats are set to 22 rather than to an exact conversion of the American convention.
