The conversion

168°F = 75.56°C

°C = (°F − 32) × 5/9, so (168 − 32) × 5/9 = 75.56.

168 °F is well outside the range outdoor air occupies on Earth, so there is no useful weather description for it — this page is arithmetic rather than a forecast.

The other direction

75.56 °C converts back to 168 °F, which is the same relationship read the other way. Going from Celsius to Fahrenheit, multiply by 9/5 first and then add 32. Adding first is the usual mistake.
