I am Appalled and Outraged!
After re-calibrating my units of measure system to the Reg's common sense and entirely practical system, q.v. https://www.theregister.co.uk/Design/page/reg-standards-converter.html, I find that this article uses a non-standard unit of measurement! Unacceptable!
I demand that The Register, if it is to maintain it's readers expected high standard of reporting, to immediately rectify the situation by using an approved Reg unit.
Given we have force (the Norris) and distance (possibly the Linguine is most relevant), I suggest The Register immediately gets to work to supply both the name of the Reg unit and it's conversion rate, particularly to this thing called a 'joule', on which I am unable find any information on the Reg's standard converter, making it, the joule, a meaningless unit.
