I've wanted to know this for years, but NO-ONE can seem to answer!

No, kilo means 1,000.
The actual SI unit of weight is the gramme. Kilogramme means 1,000 grammes.
Sorry, the SI unit is actually the Kilogramme, but it is still 1,000 grammes

Its to make derived units a more convenient size. The base units of SI were taken from competing systems - the gramme was already defined. However, the choice does make electrical units an inconvenient size - the capacitance of the entire Earth in SI is only a few Farads for instance.

Basic unit of mass is gram and 1000 grams = 1 kilogram
The quantity of 1 gram mass is quite small for everyday life. So in SI unit a convenient unit is chosen for everyday life, and it is 1 kilogram.
Similarly, 1 cc (cubic centimetre) is small for everday use when you are measuring volumes of milk, water, etc. Accepted unit is 1 litre = 1000 cc = 1000 ml.
For juice, millilitre = cc is used when you are talking about juice-pack-with-straw, normally 250 cc or 250 ml. But for a can of juice, acceptable sizes are, 1.89 litres, 3.78 litres, etc. For milk you may find some small container with 250 ml or 500 ml.
So the choice is for convenience.
SI unit of 1 kg is just another example for scientific convenience.

kg = 1 X 10^3 grams; the "power of 3" is for the "gram" part of kilogram.
Thus, for grams, there are 1,000 of them, which is why 1,000 of them together are called a kilogram (1,000 grams = 1 X 10^3 grams because 1,000 = 10^3 = 10 X 10 X 10)

Who says a kilogram is the base unit? It is used often because a kilogram is comparable to a pound (2.2 lbs. actually) which is something we are familiar with but I would not say it's the base unit.

Well this is an exception
This is mainly because kilogram was more convenient but at that time all these units were already in use
So it was difficult to change them

kilo means multiplied by ten to the power three

Kilo means thousands (..power of 3..)
One kilo-gram is 1000 grams.
The relationship is obvious, is it not? : - )
