Your question is rather like asking, 'How many miles per hour do you do in one hour?' A watt is simply the rate at which you use energy or do work, and it is the same regardless of over what period it is measured.

How many kilowatt hours - KWh - are used to light a 30 watt light bulb for 1 hour?
A kilowatt is 1,000 Watts. 30 Watts is equal to 0.03 kilowatts. A kWh or kilowatt-hour is the rate of electrical usage. It is a measure of kilowatts used per period of time (1 hour). 1 kWh is 1 kilowatt (1,000 watts) for 1 hour. So, multiply your 30 watts (0.03 kilowatts) by 1 hour to get kWh. =0.03 kWh In about 33 hours and 20 minutes, this lamp would use 1 kWh.
How much energy does a 1000 wate high pressure sodium lamp use?
400 W HPS bulb: actual wattage pull would be around 440-480 watts when it is on
How do you compute electrical consumption of a device?
A simple electrical device is a 60 watt light bulb. The bulb is consuming 60 watts of electricity from the moment you turn it on. If you keep that light bulb on for 10 hours the power used is 60 watts x 10 hours = 600 watts of power. Electricity is sold in Kilowatt Hours. A Kilowatt is 1000 watts of power. Depending on the state you live in, it sells for 7 to 18 cents per Kilowatt Hour. So if you leave that light bulb on 10 hours per day for 30 days you will have used up 600 watts x 30 days = 18,000 watts of electricity = 18 Kilowatt Hours. At an average cost of 10 cents per Kilowatt Hour that bulb costs you $1.80 per month to leave on. The formula is watts x time x cost per Kilowatt Hour = cost of use...Answer provided by Gene Evangelist
How do you calculate BTU heat gain based upon electric watts?
1 Watt = 3.412141633 BTU/hour, so multiply the number of watts (that are converted to heat) by the factor, to get BTU per hour. Multiply this by the number of hours that it is running, to find BTUs.
How many watts could a solar panel generate in one day?
The watt is a rate of delivery or use of energy (1 Joule per second) Anything called watts per day means an increase in power per day. (100 watts first day, 200 watts second day, 300 watts third day etc). I'm sure you don't mean that. Direct ("normal" ) sunlight that falls on a square metre is up to about 100 Watts so you'll never get more power from that even with 100% efficiency. Consult the brochures. Probably a few tens of watts per square meter. Energy per day is watts x time-of-sunlight (direct, near 90 degrees). Which will be Joules. 3600x1000 Joules equal 1 Kilowatt-hour, sometimes called "1 unit".
How many watts does a charger use per hour?
about 15 per hour its not a lot
How many watts are used in a solar cell per hour?
100 watts
How many watts does a fan use per hour?
3/4 of watts
How many volts per hour does a 75 kva transformer produce?
Volts per hour is an invalid statement. You may have meant Watts per Hour.
How many watts does an average printer use?
about half as many watts as the computer per hour a computer uses 200-500
How many volts per hour when they say 800 watts?
There is no valid conversion.
How many kilowatt-hours do 50 w used for 12h equal?
A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.
How many watts can a 20 amp breaker handle per hour?
2.3 kw per hour on a 110-120 volt circuit.
How many watts are used in the average home every hour?
The number of watts used per hour is defined as a watt-hour or "wh". Electricity is normally billed as kilowatt hours or 1,000 watts per hour. Your electric bill will give you KWH number for the month so you could divide this by (24 x 30) to get an hourly average. As an example of the wide range of usage I have a town house rental that used 20 KWH in a month, and another large residence that used 2,900 KWH in a month. In this case the smaller house averaged 27.7 watts per hour and the larger house 4028 watts per hour.This answer is incorrect. A watt hour is not 'the number of watts used per hour'. It is the number of watts times the number of hours. There is no such thing as 'watts per hour'.
How many watts are needed to use 1 kilowatt an hour of hydro?
Hi well kilo means 1000 so thtas 1000 watts per hour
How many watts does a mini refrigerator use per day?
A mini refrigerator uses about 70 watts per hour or 0.07 KWH.Therefore it uses about 24 times 0.07 KWH, or 1.68 Kilowatt Hours per day.There are varied sizes of "mini refrigerators" and varying degrees ofinsulation, so the wattage may vary from 40 watts per hour to 100 watts per hour or .96 KWH to 2.4 KWH per day
How many watts per hour will a unit that is rated at DC 12V 500mA consume?
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
