4300 meters = approximately 14107.61 feet.
Boiling point is 212 degrees Fahrenheit at sea level.
(Each 500 feet increase in elevation will be lowered by approximately 1 degrees Fahrenheit)
14107.61 feet divided by 500 feet = 28.21522
So the boiling point would be lowered by about 28 degrees Fahrenheit at 4300 meters above sea level. Which will make your new boiling point 184 degrees Fahrenheit instead of 212.
184 degrees Fahrenheit = 84.4 degrees Celcius
