About 90°F to °C
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. Swimming pool and spa temperatures are often listed in Fahrenheit in the US. A comfortable pool temperature of 78–82°F converts to 26–28°C — the standard range used internationally. The formula for converting Fahrenheit to Celsius is: °C = (°F − 32) × 5/9. Subtracting 32 accounts for the difference in zero points, and multiplying by 5/9 adjusts the scale size.
