Why is the kilogram the 'base unit' of mass instead of the gram?

The SI sytem of units would have been more elegant if the gram instead of the kilogram had been chosen as base unit of mass. Why and when did they choose the kilogram as base unit?

Are others actually reading his question? 

Yes when using metres of things they are more likely to weigh kilograms but why define a gram as 1000 times less than what would be used with other base units?

The original kilogram was 1 dm^3 of water. So why not define *that* as a gram?
