5.5 watts is 0.0055 kilowatts. in one hour the equipment uses 0.0055 kilowatt-hours.
The fridge consumes the watts. My fridge is a normal one, it consumes 500 watts for 2 minutes every hour.
A typical iron uses 1000 watts all the time the heating element is working. It is controlled by a thermostat so the element might be on for a quarter of the time. In an hour the iron might consume 250 watt-hours or 0.25 of a unit.
an 1100 watt microwave wil generaly consume aproximatly 3.0 wats when not in use and close to 1100 watts while in use, the internal light while the door is opn will consume about 32.4 watts. There are 1000 whats in a Kilowatt hour.
Your question is rather like asking "How many miles per hour do you do in a week?" You don't consume watts over time, it's a measure of how many joules of energy you consume over time.
It depends on what kind, but normal water purifiers need 300~450 watts per hour.

When 1000 watts of power is consumed over a period of 1 hour, the consumption is 1 kw/h.
2.4705 watts/hour

Watts are units for measuring the rate of energy consumption. So it is meaningless to speak of how many watts something consumes in a length of time. (It would be like asking how many miles per hour a car drives in an hour.)Energy consumption may be measured in kilowatt-hours. A typical microwave consumes 1500 watts, which would be 1.5 kilowatt-hours in one hour.

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
One kilowatt hour (kWH) is the amount of power used at the rate of 1000 watts for one hour. Therefore a device of 120 watts running for one hour would consume 120 / 1000 x 1 = 0.12 kWH
A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWH) of electricity.
KWH stands for kilowatt hour, meaning a thousand watts used for an hour. In terms of, for example, the familiar 60 watt light bulb, you would need (just under) 17 such light bulbs operating for an hour to consume 1 KWH.
