Now explain, in clear English, why the derived units i.e. newton, pascal, joule
Are capitalised when abbreviated i.e. N, Pa, J.
But written in lower case when in long hand i.e. newton, pascal, joule.
Eventhough they are named after real people i.e. Newton, Pascal, Joule.
And why is the kilogram the odd one out? It should be the gram.
