The conversion
73°C = 163.4°F
°F = (°C × 9/5) + 32, so (73 × 9/5) + 32 = 163.4.
73 °C 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.
Convert something else
68°F
Worked example: (20 °C × 9/5) + 32 = 68 °F · 20 °C + 273.15 = 293.15 K

The other direction
163.4 °F converts back to 73 °C, which is the same relationship read the other way. Going from Fahrenheit to Celsius, subtract 32 first and then multiply by 5/9 — doing it in the other order is the usual mistake and produces a plausible-looking wrong answer.
