How many watts in 1 kilowatt?
There are 1,000 Watts in a Kilowatt. One Kilowatt is equivalent to 1,000 Joules per Second. The prefix Kilo means 1,000 and Watt means Joules per second.
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.
Unfortunately, the question as phrased is meaningless. A watt or kilowatt is a measure of voltage times current - one kilovolt at one amp of current dissipates one kilowatt of energy, but the same kilovolt at one tenth of an amp of current only dissipates 100 watts. Here's the formula: Watts = Volts * Amps
Examine your television set; somewhere at the back, you should see how much watts it uses. If it doesn't, look for volts and ampères, and multiply those to get watts. A kilowatt is 1000 watts; a device that uses 1000 watts will use 1 kWh per hour; one that uses 100 watts will use 0.1 kWh per hour, etc.
A kilowatt hour is not in and of itself a measurement of time. It is power in watts (more specifically kilowatts) multiplied by time in hours. A kilowatt is equal to 1000 watts. If a device uses say 2500 watts for 1 hour, that is equal to 2.5 kilowatt hours. If that same device is used for 2 hours it is equal to 5 kilowatt hours. Right. And it is power multiplied by time, which…
A middle classed home uses 9.6 mega watts a year (9.6 million watts) divide that by 365 and you'll get the answer. Answer A watt is an instantaneous measurement of the rate at which you consume energy. Therefore, there is no such thing as 'watts per day'. You should be asking 'How many kilowatt hours does a house use in a day?', because a kilowatt hour is an unit of energy.
