50 W * (1 kW/1000 W) * (10 hr/day) = 0.5 kW-hr/day
Assuming 30 days/mo.--> 0.5 kw-hr/day*(30 day/month) = 15 kW-hr/month
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
Use the formula: energy = power x time If energy is in watts and time is in hours, power will be in watt-hours. Divide that by 1000 to get kWh. Alternately, you can convert watt to kilowatt before doing the multiplication - in that case, kilowatt x hours = kilowatt-hours.

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.
New York City consumes about 39.4 million kilowatt hours annually.
Kilowatt hours.
The watt is a unit of power and power is consumed/dissipated instantaneously and continuously. In other words the watts are used now.Power consumed over a period of time is energy. The most common unit of energy used in the electrical field is the kilowatt-hour. But one could also use a unit of watt-year (8.76 kilowatt-hours) or watt-day (0.024 kilowatt-hours) if one wanted to.
Kilowatt-Hours
The kilowatt hour is just a unit of measurement for energy, it isn't bad for energy in any way.
We are talking about two different quantities, here. The watt is used to measure power, which is the rate at which your device is consuming energy. The kilowatt hour is used to measure how much energy has been consumed (or the work done) over a specified period of time. So you cannot simply convert one to the other. However, if you know the rate of consumption of energy, in watts, then you can determine how much energy, in kilowatt hours, your device consumes if you specify for how long that device is operating.For example, in one hour, your 60-W device will consume (60/1000) x 1 kilowatt hour. In 'n' hours, it will consume (60/1000) x n kilowatt hours. In other words, first convert the power in watts into power in kilowatts, then multiply that by the number of hours the device is operating.
Energy = power x time. Convert the numbers into compatible units, and multiply. If you multiply watts x seconds, the answer will be in joules. If you multiply kilowatts x hours, the answer will be in kilowatt-hours.
It is not power which is measured in homes, but energy consumption. Electricity companies charge for energy consumption in kilowatt hours (kW.h). This is done using an energy meter (also known as a 'watt-hour meter' or 'kilowatt-hour meter'), which monitors the supply voltage, and the in-phase component of the load current.
100 watts × 10 hours = 1000 watt hours = 1 kilowatt hour (= 1 kwh) = 1 unit of electricity.
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
on average how many kilowatts does a house use per day in electricity / gasAnswerA kilowatt is a unit of power, which is the rate at which you consume energy. The amount of energy consumed is expressed in kilowatt hours. So your question should read: "How many kilowatt hours of energy does the average home consume over the period of an hour?" As expressed, your question is meaningless, because you do not 'use' kilowatts.The answer is difficult, because it depends on the size of your house, the number of occupants, where you live (cold vs hot climate), the type of appliances you use -e.g. air conditioning, central heating, etc. If you think that your home is typical, check out your electricity bill -it will tell you have many kilowatt hours you've consumed over the billing period. It's then a case of simple mathematics to determine how many kilowatt hours you consumed over one hour.
There is no such thing as a "kilowatt per hour". Kilowatt is a unit of power, not of energy. A unit of energy is kilowatt-hour. That's kilowatt times hours, not "per" hour ("per" implies division, not multiplication). If a generator produces 10 kilowatts, that means it produces 10 kilowatt-hours every hour.
