Terra -- standard surface pressure is about 1012mb or so, but low pressure is always defined in a relative sense, e.g. it is lower than what surrounds it. There was a dying tropical cyclone a few years back in the central Atlantic with minimum pressure of around 1020mb...not impressive, but the surface pressures all around it were abnormally high. The same storm, as it developed, neared hurricane intensity (if I recall correctly) at around 1000mb.
