Pressure is very often determined by measuring the shift of the spectral line(s) of an internal calibrant. The precision of the determined pressure depends basically on the error of the peak position. A theory on how to calculate the pressure errors arising from the statistical uncertainty of the spectral peak positions is described here. Equations are presented which allow one to calculate the precision of the pressure from the spectra of the internal calibrant.
