The convention in New Zealand is to use "ton" for Imperial measure, and
"tonne" for metric. There is therefore no misunderstanding here on this pint.
No so with the USA and Imperial billion, and trillion. Although it has to be
said that with repeated usage, the Imperial meaning has faded a lot in
peoples' minds.
So "doing the ton" means "driving at 100 mph", not at 100 kph
> which equals 6x10^^21 tons (using the 1000kg ton)
>
> i.e. short (imperial?) scale and metric units ;-)
