1 ppk = 1000 ppm since ppk stands for "parts per thousand" (the "k" coming from the metric root "kilo" as in "kilometer")and ppm stands for "parts per million". For example, "350 ppk salt" means that if your mixture were divided into 1000 parts, 350 of them would be salt, or "three hundred fifty thousandths are salt". It's kinda like percent, only with 1000 or 1,000,000 instead of 100.
To convert from ppk to ppm simply multiply your number by 1000 (since each ppk is the equivalent of 1000 ppm's).
Ppk has nothing to do with the metric conversions and a power of 10. Ppk stands for the process capability as measured with the Standard Deviation of the parent population.
the Ppk index is a value calculated around if a process is normally distributed, how many standard deviations the average is away from the closest specification limit. By definition a Ppk of 1.0 represents 99.97% of the population or < 2700 parts per million or ppm out of specification. A Ppk o 1.33 represents < 15 Parts per million out of specification.
