What does liters per kilowatt hour mean?

Answer 1

That means kilowatt times hour - a power of 1 kilowatt, over a time of 1 hour, would give one kilowatt-hour. It is, therefore, a unit of energy (equal to 3,600,000 joules, since a joule is a watt-second).

Answer 2

Liters per kilowatt hour is a measure of energy efficiency for vehicles, specifically how many liters of fuel are consumed for each kilowatt-hour of energy produced. It is often used to compare the energy efficiency of different vehicles or power generation systems. A lower liters per kilowatt hour value indicates higher energy efficiency.

Answer 3

I don't know in what context you saw that, but that looks as if for every unit of energy (kWh) spent, you get a certain number of liters of ... something.
