KH/GH unit of measure questions

ppm and mg/ are the same.
Somebody on here will post an equation for you. I'm not into all that rocket science. I always look for the plain language.

As already said, for our purposes, ppm and mg/l are the same.

One KH degree (or GH dregree) is the equivalent of 17.86 ppm CaCO3.

Whoops, dropped a digit. It is 17.86 ppm.

thanks I can figure it on my own now

your ppm tested/17.86= degrees of hardness
