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.

How you convert 36watts in joules?
Watts is a unit of power; Joules is a unit of energy. Watts means Joules/second, so you would need to know how long a machine that uses 36 watts (for example, certain light-bulbs) is used.36 watts is simply 36 Joules per second; this is the same as 2160 Joules per minute, or 129,600 Joules per hour.Since the electricity bill is measured in kWh instead of Joule (1 kWh = 3,600,000 Ws = 3,600,000 Joule), you might also say that a device that uses 36 watts uses 0.036 kWh every hour.
How dou you convert joules to watts?
Joule is a unit of energy, watt is a unit of power. Power is energy per time unit. In a way, those are incompatible units, but if you know in what time you spend a certain amount of Joule, you can convert to Watt, and vice versa. For example, if you use 200 Joule in 2 seconds, that is 200/2 = 100 Joule/second, or 100 Watts. Or, if a light-bulb uses 35 Watts, that is 35 Joules every second, so in an hour it will use 35 x 3600 = 126000 Joules, or 126 KJ.
What is the equation of converting horsepower to joule?
Horsepower is a unit of power, but joules is a unit of energy. To convert horsepower to joules, you need an additional time parameter. One horsepower is about 745.7 watts. So a horsepower-hour is 745.7 watt-hours. One watt-hour is 3600 joules. A horsepower-hour is then 745.7 times 3600 = 2684520 joules.
How many watts per hour to equal 1000 btu's?
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

How many units per hour utilized by a 45kw motor?
watt (w) means joules per second. kW (kilowatts) means thousands of joules per second. Multiply that by 3600 to get the joules used per hour.
60-watt light bulb in jouls?
To calculate the energy used by a 60-watt light bulb in joules, you need to convert the power (watts) to energy (joules). First, convert watts to joules per second (1 watt = 1 joule/second), then multiply by the time the light bulb is on. So, for example, if the light bulb is on for 1 hour (3600 seconds), the energy used would be 60 watts * 3600 seconds = 216,000 joules.
If a shaft is developing 25 watts of power per second how much work it can do in one hour?
To calculate the total work done in one hour, first convert 25 watts to joules per second. Then, multiply this value by the number of seconds in an hour (3600 seconds). This will give you the total work done in one hour.

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

Calculate number of joules in 1kwh?
1 Watt = 1 Joule/second 1 kilowatt = 1000 Watts = 1000 Joules/second 1 hour = 60 minutes = 3600 seconds 1 kWh = 1000 (Joules/second) * 3600 (seconds) = 3,600,000 Joules = 3.6 MJoules
How many joules of energy go in a radio?
Radio waves are energy. Electromagnetic energy to be exact. The amount of energy a radio wave has will depend on the amount of power the transmitter has, the amount of amplification, the quality of the cable connecting it to the antenna and finally the antenna. The amount of energy is usually measured in watts.
How do you convert joule per hour into joule per gram?
To convert joule per hour to joule per gram, you need a material's specific heat capacity. Multiply the joules per hour by 3600 (since there are 3600 seconds in an hour) to get joules per second. Then divide by the specific heat capacity of the material in joules per gram per degree Celsius to obtain joules per gram.
Do they rate watts by the hour?
in electronics, there is a term of Watt Hours used in power bills and things. watts itself is a unit derived by 1 joule per second. in order to get watt hours (which is just 1 joule per hour) you multiply your watts (joule/second) by 360 (60 seconds in a minute multiplied by 60 minutes in an hour). that will then give you units of joules/hour
How do you find how much energy is transferred in an hour joules?
To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).
How many kw in a kj?
1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds. So 1 kWh is 3,600,000 Joules, or 3600 kJ.
