32 deg F is freezing point. -18 deg F = (18+32) = 40 degrees below freezing point. (Fahrenheit scale).
0 C = 32 F 100 C = 212 F 180 degrees F equals the measurement of 100 degrees C 9 degrees F therefore equals 5 degrees C -40 F is 72 degrees F below freezing -40 C is 40 degrees C below freezing Convert F to C 5 times -72 is -360 divided by 9 is -40 C convert C to F 9 times -40 is -360 divided by 5 is -40 F
Yes, many people would consider it cold. It is eight degrees above freezing.
The only one of the five that is "below freezing" (32°F) is the 25°F, and ice would normally only form below the freezing point.
Let T = temperature T is less than 40 degrees. T < 40 degrees
