About 399°F to °C
A useful mental shortcut: subtract 30 from the Fahrenheit value and halve it. This gives a rough Celsius estimate — accurate to within a few degrees for common temperatures. US weather forecasts use Fahrenheit. Temperatures like 72°F (a pleasant 22°C) or 95°F (a sweltering 35°C) need to be converted to make sense for international visitors. Body temperature readings on American thermometers use Fahrenheit. Normal body temperature of 98.6°F equals 37°C. A fever above 100.4°F means above 38°C — useful to know for medical care abroad.
