Energy in kilowatt-hours (kWh) to power in watts (W) calculator and calculation formula.

Energy in kilowatt-hours (kWh) to power in watts (W) calculator and calculation formula.

## How do I convert kilowatts to watts (W)?

## Kilowatts-hour to watts calculation formula

P=The power P in watts (W)

E=the energy E in kilowatt-hour (kWh)

t=the time period t in hours

**P(in W) = 1000 × E(in kWh) / t(in hr)**

So that you can re-write this formula as

**watt(p) = kilowatt-hour(E) / hour**

or you can re-write this formula as

**W = 1000 × kWh / h**

**Lets take one example**

**Example#1**

I want to Calculate the the power consumption in watts when the energy consumption is 21 kilowatt-hour for time

periods of 6 hours?

P = 1000 × 21 kWh / 6 h

= 3500 W

**What is kWh?(Kilo Watt-Hour)**

A kilowatt represent unit of power, about 4/3 hp.if An electric kettle is rated with 2000 W, would be 2 kilowatts.

**Power * time is energy.**

So a kilowatt-hour is a unit of energy .One can think of a kilowatt – second is a cup – kelvin.

So our jug using 1.8 kw, holds say 7 cups.We want to raise it from say 25 C to 85 C for our coffee, so we need 60 kelvins * 7 cups = 420 cup-kelvins.

This is delivered at 1.8 kw-s, so we divide by 9/5, of multiply by 5/9. 5*210 = 1050, divide by 9 gives 116.6 seconds.So your jug takes about two minutes to boil.

The unit is what one buys electricity in. A television running at 333W for 12 hours gives 12*333/1000 = 4 kWh.

Find out how many watts are completed in an hour.

If you have a 80W CFL LIGHT bulb, and in each hour the CFL LIGHT bulb is turned on, it consume 60W of power.

**Step for conversion:**

you have to Divide the number of watts by 1000.so that number in watts converted to kilowatts.

80W/1000 results is 0.08kW.
