kilo Watt per hour


Explanation:
wikipedia:

One watt hour is equivalent to one watt of power consumed for one hour. This is equivalent to 3,600 joules. For example, a sixty watt light bulb would consume 60 watt hours of energy every hour. Similarly, a 100 watt light bulb would consume 50 watt hours in thirty minutes.

The watt hour is derived from the multiplication of the SI unit of power (watt) and the non-SI unit of time (hour).

The kilowatt-hour is commonly used for electrical energy and natural gas energy. This may be because domestic appliances often quote power in kilowatts. Many electric utility companies use the kilowatt hour for billing. Megawatt-hours are used for metering of larger amounts of electrical energy. For example, a power plant's daily output is likely to be measured in megawatt-hours.

The Board of Trade Unit or B.O.T.U. is an obsolete UK synonym for kilowatt hour. The term derives from the name of the government department that regulated the electricity industry. The B.O.T.U. should not be confused with the British thermal unit or BTU, which is a much smaller quantity of thermal energy.

I take it all back now...

here's a clearer article:

First things first. The kilowatt-hour (kWh) is not a unit of power. It is a unit of energy. Here's why:

The kW is a unit of power. It is 1000 W or 1000 J/s.

By definition:

EQUATION: power = energy / time

Rearranging this we get energy = power × time

If we choose to measure power in kW and time in hours, we have:

energy (kWh) = power (kW) × time (h)

The kilowatt-hour (kWh) is a unit of energy. But how much?

We have seen that: energy (kWh) = power (kW) × time (h)

Normally we want energy in joules (J) and time in seconds (s). The kW above is 1000 W (1000 J/s). The hour is 3,600 seconds, so:

1 kWh = 1,000 J/s × 3,600 s

1 kWh = 3,600,000 J

1 kWh = 3·6 MJ (mega joules: see prefixes)

The kWh is a large unit of energy used to measure how much energy is used in homes.

agree  Tony M: Yes, although to be pedantic, do let's note that the abbreviation is kWh, but when you write 'watt', it takes the l/c (Unless it is the great man's name!)

disagree  David Knowles: It's not kilowatts per hour, as the Wikipedia hour shows. Its kW multiplied by hours.
9 mins
neutral  PAS: to be fair, the wiki article is not patently wrong, but it is misleading if you're not careful...
