I don't know if its in the British manuals, but the front of my shop manual has a section titled 'Glossary of Part Names and Alternatives' which gives the name for a part, then some synonyms.
For some, its the name I would normally use. For others, one of the synonyms seems more appropriate. For example, I would normally call it a 'muffler' rather than a 'silencer' or 'expansion box'
On my 2006 Speed Triple, the instrument cluster can be toggled through several screens, where information like speed, average speed, time elapsed, and fuel consumption are displayed. It can also be set to display in KPH/Liters, Miles/Gallons, and Miles/Imp. Gallons. At first, I thought I was getting fantastic mileage, only to realize the clocks had been set to Imperial. Instant 20% reduction in mileage.
Apparently, Imperial gallons are still used somewhere.
Can one still get bitter by the Imperial pint?
