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.
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.
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.
Volts per hour is an invalid statement. You may have meant Watts per Hour.
This has no physical meaning. The correct unit for power is the watt (not watt per 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
kWh, kilo Watts per hour
Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).Power. In SI, energy is measured in Joule, and power is measured to watts (= Joule per second).
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
there is 5 lumen per hour in 1 joule
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.
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.
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.
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, alsocalled 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, alsocalled 1,000 watt-hours., or one "kilowatt-hour".The usage on your electric bill is listed in 'kilowatt-hours' (KwH). One of thosecosts 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.
A watt is the SI unit of power. It's equivalent to one joule per second.
A kilowatt is 1000 watts, and 1 watt is 1 joule per second
To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.
