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).
