Question:
At sea level, how many inches of mercury (vacuum) is required to boil water with an ambient temperature of 80F?

Replies:
The standard atmospheric pressure at the Earth's surface of one atmosphere is equal to 1013.25 millibars is equal to 101,325 Pascals. To avoid large numbers, air pressure is reported in hectoPascals, which are the same as millibars.
