Try this: 100 C divided by 5 is 20 which is multiplied by 9 to get 180, then add 32 to arrive at 212 F.

You try this, 200 C divided by 5, then multiply by 9 and add 32.

Water that hot will very severely burn your skin. The severity of tap water scalds depends on the temperature of the water and the length of time the skin is exposed.

Human exposure to hot water at 140°F can lead to a serious burn within 3 seconds, whereas at 120°F a serious burn takes about 10 minutes.

Even 100 F is too hot for the human body over an extended time period. Recall our healthy value is 98.6 F, with the surroundings being lower so we can lose heat!
