Does anyone know how to measure or determine the wire size.

If I need to check, I use a vernier caliper to determine the diameter of
the strands ( 2*r )and then calculate the total cross-sectional area as (
pi*r^2 ) * number of strands.

This gives a result in mm^2. Which is the standard measure in most of the
world.

To do the same you'll need a chart to convert from cross-sectional area to
AWG. Google will find you one.
