Hitherto, solid fat contents often have been expressed as dilatations. Since the development of pulsed NMR into a quick and accurate method for the determination of the solid fat content, while wide‐line NMR still is being used, accurate equations are needed to enable conversion from dilatations to NMR values and vice versa. The inaccuracies arising when NMR values are converted into dilatations are almost equal for the various NMR methods. The direct pulse method in which one mean solid fat factor f is used is the most attractive method to replace dilatometry. For further reduction of the standard deviation when converting NMR values into dilations and vice versa, it will be necessary to split up the fats into groups with similar compositions.
