Geography::NationalGrid::GB uses that NATGRID projection by default
and you need WGS84 for Google. From looking at the source it looks as
if you can pass a Projection option to the constructor to specify
which projection to use. The shift between the two projections is
certainly about right to account for your error.
Is that reasonable?
Disclaimer: I haven't used Geography::NationalGrid::GB but I have my
own code that does the same thing.
