Abstract The use of resonances to calibrate the momentum scale is discussed. Formula for the relationship between the magnetic field scale and the measured mass are derived and applied to the decays J/$\psi \rightarrow \mu^+ \mu^-$, \ks $\rightarrow \pi^+ \pi^-$ and $\Lambda \rightarrow p^+ \pi^-$.
