As we know, unit of Work is Nm (Newton-metre). Do you know why in Nm, 'N' is capitalized here but not 'm'?

If the unit is named after a person, the symbol is capitalized (first letter only), but the other letters are not capitalized. That's why, in Newton-metre, 'N' is capitalized because Newton (a unit of force) is named after Isaac Newton. Similarly, The Watt (after James Watt) for measuring units of power.
