I know but USA imperial units are different from UK ones, just like how american english has some differences with standard english.
I assumes they were using USA imperial units since IIRC UK now also uses metrical units to some degree eg: they use centimeters to measure people’s height
To be very pedantic, in the USA they’re not imperial (we left the British Empire, we had a whole war about it), they’re “US Customary Units” and they’re defined in metric lol
They prolly did not use american imperial units tho
Imperial units didn’t come from America.

Edit: i may have confused UK and Canada in the last paragraph https://en.wikipedia.org/wiki/Metrication_in_the_United_Kingdom
