minus-squareEl Bartolink2•11 months agoThanks! I knew what PPM was, but I was having trouble visualizing how much chlorine was that in, say, a liter of water. And there you go. 1 mg per liter does the trick, and it’s standard!
What’s PPM in this context? Like, one drop in a bucket?
“Parts-per-million”
Ok but what about in this context?
1 mg of chlorine per 1 litre of water
1 mg or 0.001 ml?
And I know 1 liter of whater is 1kg.
