Where the jam is eaten in quantities so high and with such ferocity that Hartley’s, Bonne Maman and Wilkin & Sons year on year report
the highest quantity of jam eaten per person per square mile than anywhere else on earth.
The IJSO (
international jam standards organisation) created a new metric unit of measurement called the Whitehaven. Much like Farads, a 1 Whitehaven is an enormous value. It is used to rank jam per person per square mile. Other towns are
usually measured in tiny fractions of a whitehaven such as micro or pico whitehavens and have the measure pW or mW.
Jam factories worldwide have a production per year that equates to 1 (one) GigaWhitehaven.
Any excess jam in is shipped to Whitehaven where the good townspeople ramp up
consumption ans not to let any go to waste. Afterwards a new measure is taken for the coming year.
There means there is always exactly as much jam across existing reserves and planned production to keep Whitehaven going for exactly one year financial year.
