Guys, not to nitpick, but the use of incorrect nomenclature is driving me, as an engineer, nuts!

Watts is a capitol W; named after James Watt

kilo (thousand) is a lower case k, mega (million) is an upper case M (don't know why)

hour is expressed as hr or just h

kW, MW, etc. These are units of power

kWhr, MWhr are units of energy (or kW-hr, MW-hr or kW-h, MW-h) as power over a time period

Let's not let James Watt roll over in his grave as James watt!

I know, I know - picky, picky. But the detail is important!
