Water boils at 100C. Room temperature is 21C. Boiling water would have to fall 79C. That's about 192 F.

Boiling water is not hot if the air pressure is low. A guy called Boyle expounded this in his law PV over C equals a constant. Odd he was called Boyle. Water boils at 100 degrees C at normal atmospheric temperature. So if you want to drink boiling water without burning yourself don't wait for it to cool decrease the air pressure. If you boil an egg on top of a mountain it takes quite a lot longer - I have done this

tea is made from boiling water.
water boils at 100 degrees centigrade at normal atmospheric pressure (if the pressure is lower such as when at high altitudes the boiling temperature is lower).
temperatures above 65 degrees centigrade are going to cause burns, i wouldnt want drink something much warmer than 55 degrees centigrade.
if you boil the water in a lower pressure you could drink it immeadiately
a fable is told of a man who was accused by priests of wrong doing, they told him that they would judge his guilt by making him hold his hand in boiling water, if he pulled out his hand he would be found guilty and executed.
the man (being of mountain stock) requested that he undertake the trial "under the eyes of the gods" .... atop the tallest mountain.
so they boiled the water and he held his hand in it....
and such was "the will of the gods" he was not even burned (as the water boiled at a colder temperature due to the lower atmospheric pressure)

If the temperature of the boiling water is apt for drinking then there is no need for cooling.

Relative to the drinker, however, for yourself...
100 degrees is boiling.
Wait till drink is drinkable.
Stick temperature gage in it to record new temperature (not through the mug).
Subtract from 100 degrees to find the difference.
That's what I'd do...

Depends on the temperature of the surrounding air and the amount of water you dropped.

Unless you want to burn your mouth just wait, time is relative.
