  The recent NASA TESS mission has the potential to increase the available
asteroseismic sample dramatically, but its precision and accuracy have yet to
be confirmed. To date, NASA's Kepler mission has been considered the gold
standard for asteroseismic samples, despite data only being available for a
small portion of the sky. TESS's observations cover the whole sky, and previous
work has identified 158,000 potential red giant oscillators. Using APOGEE,
which is calibrated to the asteroseismic scale of the Kepler data, we show that
seismology from TESS is calibrated to the Kepler scale to better than 5% for
about 90% of red giants, and has only slight trends with mass, metallicity, and
surface gravity. We therefore conclude that current TESS seismic results can
already be used for galactic archaeology, and future results are likely to be
highly transformational to our understanding.
