We've seen many places that PV = nT but T is temperature, not heat.

Another nit if you will to pick:

PV = nkT

Universal gas law - this is applicable to 'ideal' gasses,
and as such, the temperature is indeed an exact measure of
the internal energy, or heat, of the gas.

Temperature in general is not the same thing as heat, but
for ideal gasses, the relation is true; knowing the temperature
allows one to calculate the exact average kinetic energy of
the gas atoms in the volume.
