What air temperature will feel four times as warm as 0 °F?

To find the air temperature that will feel four times as warm as 0 °F, we need to convert 0 °F to Celsius and then multiply it by four.

To convert Fahrenheit to Celsius, we use the formula:

°C = (°F - 32) / 1.8

Let's substitute 0 °F into the formula:

°C = (0 - 32) / 1.8
°C = -32 / 1.8
°C ≈ -17.78

Now, since we want a temperature that feels four times as warm, we need to multiply -17.78 by four:

4 * -17.78 ≈ -71.12

Therefore, the air temperature that will feel four times as warm as 0 °F is approximately -71.12 °C.
