Keep diluting it up to a trillion times larger volume than your stock solution
It's equal to 0.0000000015 percent. Think of this way: 15 parts per thousand is 15/1000 = 0.015 or 1.5 percent. 15 parts per million is 15/1E6 = 0.000015 or 0.0015 percent. 15 parts per billion is 15/1E9 = 0.000000015 or 0.0000015 percent. And 15 parts per trillion is 15/1E12 = 0.000000000015 or 0.0000000015 percent.
668 ppm stands for 668 parts per million. It is a unit of measurement used to describe the concentration of a substance in a solution or mixture. In this context, it means that there are 668 parts of a particular substance for every 1 million parts of the solution or mixture.
The human brain is the most complex thing in existence (so far). It can make 100 trillion calculations per second. The human brain is the most complex thing in existence (so far). It can make 100 trillion calculations per second.
1000 micrograms is 1 milligram. so this is 1 milligram per millilitre, i.e. 1000 milligrams per litre. Parts per million is milligrams per litre. Therefore there are 1000ppm in 1000 micrograms per millilitre.
Depends on the quantity...maybe you are think of parts per million?

Natural plutonium exist in uranium ores in extremely traces - parts per trillion or less.
Natural plutonium exist only in extremely traces (parts per trillion) in uranium ores.
parts per million = mass of solute / mass of solution X 1 000 000
they make up to 500 trillion per decade
