What is the standard atmospheric pressure expressed in pascals?

Explanation:
Standard atmospheric pressure at sea level is defined as 101,325 pascals. That value is the SI definition of 1 atmosphere, and it equals about 101.325 kilopascals (101,325 Pa = 101.325 kPa). So when asked for the standard atmospheric pressure in pascals, the exact value is 101,325 Pa. The other numbers aren’t in pascals or are off by a factor: 1013 lacks units and would be far too small in pascals; 1013250 Pa is ten times too high; 10132 Pa is about two orders of magnitude too low.
