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.
5.5 watts is 0.0055 kilowatts. in one hour the equipment uses 0.0055 kilowatt-hours.
FIRST CHECK HOW MANY WATTS DOES ALL YOUR ELECTRICAL APPLIANCES CONSUME THEN DIVIDE IT by their respective volts you will get your required answer
The fridge consumes the watts. My fridge is a normal one, it consumes 500 watts for 2 minutes every 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.
A small coffee grinder 100-200 watts.

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.
Usually about 1200 to 1500 watts.

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
"Watts RMS" is better represented as "Watts average". Since 1000 watts is 1kw you have "1000 watts average" and you can derive "1Kw average". So 1000 watts RMS will consume 1 Kw
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
