To convert from g/l to ppm multily by 1000. For example: 0.100 g/l of CaCO3
would be equivalent to 100 ppm carbonate hardness. Are you sure the numbers
are in g/l and not mg/l? My water anaysis list the mineral content in the
latter ( mg/l ). In this case the conversion is really simple ( you multiply
by 1 :-).
