Actually it's 10.6 imp = 12.73 USG

However, starting in middle america and driving that  tank of water
up to visit Mark in Alaska, in the depths of winter, the water will
freeze and thereby expand, either forcing the cap off or stretching
the plastic container to 13.2 gals occupied space. Alternatively,
heading south to Baja, the rise in temp will also cause the required
3.69% expansion in volume.

See how wise those clever German engineer types were.
