How do you measure watts per hour?

You'd have a tough time, since "watts per hour" is a meaningless unit.

"Watt" all by itself is a rate ... the rate of energy consumption or flow.

"1 watt of power" means "1 joule of energy per second".

If you use one watt of power, you use one joule of energy every second.

If you keep using it for an hour, you've used 3,600 joules of energy, also

called one "watt-hour" of energy.

If you use 1,000 watts of power, you use 1,000 joules of energy every second.

Keep that up for an hour, and you've used 3,600,000 joules of energy, also

called 1,000 watt-hours., or one "kilowatt-hour".

The usage on your electric bill is listed in 'kilowatt-hours' (KwH). One of those

costs you anywhere between 10¢ and 25¢ .

"Watts per hour" makes as much sense as "miles per hour per minute".

That's acceleration, which is another whole different story.

How many miles per hour is 100 watts?

There is no direct conversion between watts and miles per hour, as they are different units of measurement. Watts measure power, while miles per hour measure speed. The relationship between power and speed would depend on additional variables such as efficiency, resistance, and the specific application.


How do you convert joules per second to watts per hour?

There is no equivalence. A Joule per second is a measure of power which is equivalent to a Watt. Not a Watt per second or a Watt per hour etc, just a Watt. The two units mentioned in the question measure different things (though I am not sure what Watts per hour measures) and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.


Is 200 watts an hour a lot of electricity?

No, 200 watts is not a measure of electricity consumed per hour, but rather a unit of power. To determine the electricity consumed per hour, you would need to know the duration the power is being used. If an appliance consumes 200 watts per hour, it's relatively low power consumption compared to appliances like air conditioners or heaters.

500 Watts per minute to kilowatts per hour?

To convert watts to kilowatts, you divide by 1,000. Therefore, 500 watts is equal to 0.5 kilowatts. To convert minutes to hours, you divide by 60. So, 500 watts per minute is equivalent to 0.5 kilowatts per 60 minutes, or 0.5/60 = 0.00833 kilowatts per hour.


What is the equation for converting 1 amp to kilowatt hour?

Amperage (Amps) is a measure of current flow Voltage (Volts) is an electrical measure of difference in potential Wattage (Watts) is a measure of power which is energy per unit time A kilowatt equals 1000 watts Kilowatt Hour (KWH) is a measure of energy (Watts x hours/1000) The relationship is: Power (Watts) = Voltages (Volts) x Amperage (Amps) Therefore, Amps = Power (KW) x 1000 / Voltage (Volts)


Is there a voltmeter that measures volts per hour?

Volts is a measure of electrical impulse or potential energy, and cannot be expressed in a number "per hour." If you're looking for a unit that represents energy consumption, you may be looking for watts (W), which is Amps (current, or voltage flow) multiplied by hours (Ah).You can measure watts with a watt-meter or consumer device such as a kill-a-watt.

How much energy is used by a streetlight per hour?

Yes, that's the question. A 1000 Watt light uses... 1000 Watts. A 500 Watt light uses, you guessed it... 500 watts. It depends on the size of the bulb. ACTUALLY... Watts are a measure of power, Joules are the measure of energy - you can simply convert watts/hour or watts/second to joules but to say that a 1000 Watt light bulb uses 1000 watts is a ridiculous thing to say =D watts are Wh-1 or Ws-1
