The '''Kendrick mass''' is a mass obtained by scaling the [[atomic mass unit]] (u) (or equivalently the dalton (Da)) by the ratio of the mass of the CH<sub>2</sub> group to 14.0000 to simplify the display of peak patterns in hydrocarbon [[mass spectra]]. The scaling factor is 14.000/14.0156.
Mass obtained by multiplying a measured mass by the ratio of the nominal mass to the exact mass of a specified elemental formula F:
:Kendrick mass <nowiki>=</nowiki> observed mass x (nominal mass of F/exact mass of F).
In the common case of the elemental formula CH<sub>2</sub>, the measured mass is multiplied by 14/14.01565.
