It's the end of the power level scale.
4500 = 100% so 9000 = ((9000/4500)*100) = 200 %
35% of 9,000 = 35% * 9000 = 0.35 * 9000 = 3,150
I think there is no reason for 9000 in ISO 9000. Probably this was number no one had used previously so was adopted. Pravin Puranik
1000 millilitres = 1 litre so 9000 millilitres = 9000/1000 = 9 litres. Simple!
1000 grams = 1 kilogram so 9000 g = 9000/1000 = 9 kg. Simple!
100,000 cm = 1 km so 9000 cm = 9000/100000 km = 0.09 km

There are 1000000 nanograms in a milligram. So 9000/1000000 is 0.009 milligrams.
A thousand thousandths is 1, so 9000 thousandths is 9.

9000 + 9000 = 18000
