The conversion

320°F = 160°C

°C = (°F − 32) × 5/9, so (320 − 32) × 5/9 = 160.

320 °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

160 °C converts back to 320 °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.
