Si standards for this stuff are nice, but theres way too many of them. Often using the exact same method to measure, but shifting the implied decimal points location. Particularly since the 'a' may be assumed to be one atmosphere, conveniently given a std value but fully capable of varying 25% according to the barometer and altitude in actual practice, at altitudes capable of supporting human life comfortably.
