One atmosphere is equal to
- 10.3 lbf/in2.
- 14.7 lbf/in2.
- 29.92 in. Hg.
Explanation
Standard atmospheric pressure at sea level is 14.7 lbf/in2 (about 101.3 kPa). This is the figure used as one atmosphere in imperial units. The value 10.3 lbf/in2 is incorrect, and 29.92 inHg is the same pressure expressed as a mercury column, not in lbf/in2.
