##### Convert Watts (w) to kilowattshours (KWh) Calculation

#### To convert Watts to KWh , Please provide the values below:

#### To calculate watts to kilowattshours , use the following formula:

**The energy (E) in kilowatt-hours(KWh) is equal to the power (P) consumed in watts (w) times the time (T) in hours(Hrs), divided by 1000.**

__For Example 01__

If an Induction motor takes 1250W power at 0.99 (lag) power factor from the AC source and runing time 5 hours. Calculate the KWh of the motor.

__Answer__

Where,

power P = 1250W , Pf = 0.99,T = 5 hours

We Know

E _{ (KWh) } = P_{w } x T / 1000

E _{(KWh) } = 1250 x 5 /1000

E _{(KWh) } = 6.25

KWh = 6.25

__For Example 02__

If an Induction cooker takes 3000W power and runing time 1.5 hours. Calculate the KWh of the Induction cooker .

__Answer__

Where,

power P = 3000W , T = 1.5 hours

We Know

E _{ (KWh) } = P_{w } x T / 1000

E _{(KWh) } = 3000 x 1.5 /1000

E _{(KWh) } = 4.5

KWh = 4.5

__For Example 03__

What is the kWh of 2,500 watts for 6.5 hours?

__Answer__

Where,

power P = 2500W , T = 6.5 hours

We Know

E _{ (KWh) } = P_{w } x T / 1000

E _{(KWh) } = 2500 x 6.5 /1000

E _{(KWh) } = 16.25

KWh = 16.25

##### Frequently Asked Questions:

## What do you convert Watts to KWh for ?

One kilowatt-hour is equal to 1,000 watts for one hour

## What is AC Circuit 1000 W in KWh ?

1 kilowatt-hours (KWh)

## What is AC Circuit 500 Watts (W),6 hrs in Kilowatts-hours (KWh)?

A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 500 VA is the equivalent of 3 KWh. This equivalence means that the power factor of that power supply is 0.95.

## What is the formula for watts to kilo Watts-hours (KWh) ?

Energy (KWh) = Active Power(W) x Time (hrs) / 1000.

## If 1500 watts is 2 hours , how much is KWh?

3 KWh

## If 150 watts is 20 hours , how much is KWh?

3 KWh

## If 1500 watts is 6 hours , how much is KWh?
