The EnergyStar site, reliable on these matters, points to an interactive calculator on myenergystar site. This estimates the real power consumption based on room size and its humidity (you must give a subjective evaluation). Another choice in the form, for determining power consumption, is to measure how much water is condensed inside every day. This works if you already have the dehumidifier running, The interactive dehumidifier power calculator is at http://www.myenergystar.com/ProductsAndDiscounts.aspx?type=dehumidifier&menu=calculator Guido (tguido56)
There are a few variables here. What the dehumidifier is used for room or whole house, relative humidity where you live and what the setting of the dehumidifier operates at. Look for the nameplate on the humidifier. There it should tell you the wattage that it operates at. If not use the equation Watts = Amps times Volts. Kilowatts per hour is what your utility meter reads and that is what you get billed for. The more the unit operates the higher the cost is to you.
Divide the wattage by the voltage - this equals amps.
Look on the nomenclatre to find your volts and amperes. Multiply them to get your watts.
1000 watts = 1 KW, so: 820 watts = 0.82 KW 0.82 KW * 24 hours = 19.68 KWH
45 watts
Hoovers use 1000 - 2000 watts
To calculate the amps, you can use the formula: Amps = Watts / Volts. So, for 2000 watts and 110 volts, 2000 watts / 110 volts equals approximately 18.18 amps.
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
1000 watts = 1 KW, so: 820 watts = 0.82 KW 0.82 KW * 24 hours = 19.68 KWH
current=watts(power)/voltage
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.

To calculate the amps, you can use the formula: Amps = Watts / Volts. So, for 2000 watts and 110 volts, 2000 watts / 110 volts equals approximately 18.18 amps.
You can't calculate how many volts with that information; you could calculate the energy - 60 watts for 15 minutes is equivalent to 54,000 joules.
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
A humidifier makes the air fresher, While a dehumidifier removes a fresh smell. A house would use a a humidifier and a museum would use a dehumidifier
