Is this measured or calculated ?
One thing is for sure, you will engender more confidence in your understanding of the car if you get your units sorted out:
kW is a power
kWh is an energy amount
Yes on the first and from where is it being measured or displayed?
Yep on the 2nd.
kW and kWh are very different metrics. It's the same as confusing gallons with horsepower. Think of kW = horsepower, kWh = gallons.
If one charges at 1 kW (or 1000 watts) for 6 hours, 6 kWh came out of the wall. If it's at 6 kW for 1 hour, it's also 6 kWh. If it's 1 watt for 6000 hours, it's also 6 kWh.
One pays for electricity at home in cents per kWh. There are a few utilities w/residential plans where they not only bill per kWh but also have demand charges, but that's rare and complicates calculations. (Demand charges aren't unusual on many commercial plans.)
Leaf has ~21 kWh usable battery but since charging isn't 100% efficient, it takes more than 21 kWh out of the wall to fully charge a dead Leaf. viewtopic.php?p=155305#p155305
has some figures, but it was before the '13+ Leaf w/optional 6 kW on-board charger.
(BTW, many .gov sites say 1 gallon of gasoline has about 33.7 kWh of energy content.)
