New reference wavelengths for atomic transitions of Mg VII and Si VII in the272-281 A wavelength range are derived using measurements from the Extremeultraviolet Imaging Spectrometer (EIS) on board the Hinode spacecraft. Mg VIIand Si VII are important ions for measuring plasma properties in the solartransition region at around 0.6 MK. The six Si VII wavelengths are 13--21 mAand 7--11 mA longer than the values in the NIST Atomic Spectra Database (ASD)and the compilations of B. Edlen, respectively. The four Mg VII wavelengths areshorter than the values in the ASD by 8-12 mA but show reasonable agreementwith the Edlen values. The new wavelengths will lead to more accurate Dopplershift measurements from the EIS instrument, and will be valuable for spectraldisambiguation modeling for the upcoming Multi-Slit Solar Explorer mission.
