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.
