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.
Electrical energy is typically measured in kilowatt-hours (kWh). This unit represents the amount of energy consumed by an electrical device operating at a power of one kilowatt for one hour.
Electric energy usage on your electric bill is measured in kilowatt-hours (kWh). This indicates the amount of electrical energy consumed over a period of time.
To find the total kilowatt-hours consumed, first calculate the total energy used by one bulb: 60 watts * 200 hours = 12,000 watt-hours or 12 kilowatt-hours. Then, multiply this by the number of bulbs (3) to get the total kilowatt-hours: 12 kWh * 3 = 36 kWh. The electrical energy consumed in the home is 36 kilowatt-hours.
To find kilowatt-hours (kWh) from kilowatts (kW), you need to multiply the power in kilowatts by the time in hours that the power is used. The formula is: kWh kW x hours. This calculation will give you the total energy consumed in kilowatt-hours.
New York City consumes about 39.4 million kilowatt hours annually.
No, megawatt is a unit of power, not energy. It measures the rate at which energy is produced or consumed. Energy is measured in units such as watt-hours or kilowatt-hours.
Watts measure power, which is the rate at which energy is consumed. Kilowatt hours measure energy usage over time. One kilowatt hour is equal to using 1 kilowatt of power for 1 hour.
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
Active energy import is the amount of electrical energy consumed or used by a customer from the utility grid. It is typically measured in kilowatt-hours (kWh) and reflects the actual electricity consumed by a user during a specific period of time.
The total energy supplied to a patio heater can be calculated by multiplying the power of the heater (in Watts) by the time it is operated for (in hours). This will give the energy consumed in Watt-hours or kilowatt-hours.
To calculate the kilowatt-hours of energy consumed by the appliance, first convert the power rating to kilowatts by dividing by 1000 (5.00 x 10^2 W = 0.500 kW). Then calculate the energy used in kilowatt-hours by multiplying the power in kilowatts by the time in hours (15.0 minutes = 0.25 hours). Therefore, the appliance consumes 0.500 kW x 0.25 hours = 0.125 kWh of energy.
The kilowatt hour is just a unit of measurement for energy, it isn't bad for energy in any way.
