To determine if your conversion is correct, we need to use the appropriate formula. The formula to convert Fahrenheit to Celsius is:

°C = (°F - 32) * 5/9

Let's plug in the values:

°C = (90 - 32) * 5/9
°C = 58 * 5/9
°C = 290/9
°C ≈ 32.22

Therefore, 90°F is approximately equal to 32.22°C.

So, it looks like your conversion of 90°F to 33°C is not correct. The correct conversion is approximately 32.22°C.
