: I can't see how one or more of these statments can be true:-18° C (0° F),54° C (-65° F),-48° C (-55° F), 10°F or -12°C.
The only error seems to be that is should be -54° C (-65° F) not +54, probably a typo.
Boiling pt of water 212° F = 100° C
Freezing pt of water 32° F = 0° C
The formula is F° = 1.8 C° + 32
-18° C = -0.4° F
-54° C = -65.2° F
-48° C = -54.4° F
-12° C = 10.4° F
So the numbers quoted ignoring the missing - are all reasonable roundings of the conversion from Centigrade to Fahrenheit.
