You don't! They are two different entities - like converting cars to washing machines!
Simply put:
Voltage is equal to resistance multiplied by current
therefore current = voltage divided by resistance
therefore a resistance of 23ohms at 230 volts will draw 10amps current.
Watts is equal voltage multiplied by current
therefore a 230volt fire drawing 10 amps equals 2.3kilowatts or 2300 watts.
Use this for one hour and your electricity usage equals 2.3Kilowatt hours, say costing approx 15p per KWH = 34.5 pence.

How many milliwatt equals 1 kilowatt?
There are 1000 milliwatts in a watt. There are 1000 watts in a kilowatt. Therefore, there are 1 million milliwatts in one kilowatt.
Convert mw to kwh?
mw (mega watt) is one million watt and that is a unit of electricity, whereaskwh(kilowatt hour) is rate of consumption of one thousand watt of electricity for one hour.AnswerFirst of all, let's get our symbols correct. There are nounits having the symbols: 'mw' or 'kwh'! Presumably, you are either trying to express a 'milliwatt' (mW) or a 'megawatt' (MW), and a kilowatt hour (kW.h)?You cannot convert either milliwatts or megawatts into kilowatt hours, as they measure completely different quantities!The milliwatt and the megawatt both measure power(not 'electricity'!). The kilowatt measures energy(which is not a 'rate of consumption'!).
What is the electricity usage of a power Circular saw?
It depends on the power rating of the saw. If it is a 1 KW (Kilowatt) saw then it will use 1 KWH (Kilowatt hour) of electricity for every hour it is used. This is equivalent to 1 unit of electricity. If it is 500 W (Watt) then it will use half this. If it is 2 KW it will use double this.
How much does it cost to operate a 1000 watt mercury vapor light?
The same as it costs to operate any 1000 watt device or combination thereof. Your electrical bill is rated in kwh or kilowatt hours. (A kilowatt happens to be 1000 watts per hour). So if your local rate is say 8.5 cents per kwh ( a typical amount ) then it will cost 8.5 cents per hour ( plus tax & service fees, etc.!) Check your electric bill and find out your exact per kilowatt/hour rate. Since this type fixture is a commercial fixture, your rate may be a higher commercial rate than most residences.
Electrical energy can be measured in units called what not watt?
All forms of energy are measured using the same units. The SI unit for energy is the joule (J). However, the unit used by electrical utility companies is the kilowatt hour (kW.h).
How do you calculate kilojoules?
A joule is a watt-second, so one kilowatt for one second is a kilojoule.
How many watt is equal to 1kilowatt?
1 kilowatt = 1000 watt ==> 1 watt = 0.001 kilowatt
How many watt-hours are in 6 kilowatt-hours?
1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
How do you convert 1500 killiwat hours to joule?
1 kilowatt = 1,000 watts1 watt = 1 joule per second1 hour = 3,600 seconds(1,500 kilowatt-hour) x (1,000 watt / kilowatt) x (1 joule / watt-second) x (3,600 second / hour) =(1,500 x 1,000 x 3,600) x (kilowatt - hour - watt - joule- second) / (kilowatt - watt - second - hour)= 5,400,000,000 joules
Is a kilowatt larger than a watt?
true
How many kilowatt hour make 1 watt?
1kilowatt = 1000 watts but you cannot compare a kilowatt hour to a watt, the extra dimension of time changes what is being measured. The watt is a measure of power. The watt second and the kilowatt hour is energy. The misunderstanding comes from our use of the term POWER COMPANY for our electricity suppliers. They bill us in kilowatt hours which is energy, not power.
How do you calculate the Monthly cost of using a 700 watt refrigerator that runs for 10 hours a day at a cost of 0.09 Killowatts per hour?
(700 watts) x (10 hours/day) x (30 days/month) x (1 kilowatt / 1,000 watts) =(700 x 10 x 30 / 1,000) (watt - hour - day - kilowatt / day - month - watt) =210 kilowatt-hour / monthWe're guessing that the actual cost of your electric energy is $0.09 per kilowatt-hour.(210 kilowatt-hour / month) x ($0.09 / kilowatt-hour) = $18.90 per month .
What is the definition of kilo watt?
A kilowatt is 1000 watts
How many kilowatts are in a watt?
There are 1000 watts in a kilowatt. The prefix "kilo" in front of the unit watt means one thousand.
How many kilowatt hours KWh are used to light a 30 watt light bulb in 8?
A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.
How many milliwatt equals 1 kilowatt?
There are 1000 milliwatts in a watt. There are 1000 watts in a kilowatt. Therefore, there are 1 million milliwatts in one kilowatt.
What cost Rate of 07 per kilowatt hour120 V and 60 Watt 24 hours?
First find your watt hours and by moving the decimal place change to kilowatt hours. Then multiply that answer by .07 cents per kilowatt hour.
