    When reading my local water summery, all values are given in mg/L. I'd like to utilize "EZ Water Calculator Spreadsheet" (see link below):

    Does anybody have a simply method of converting from mg/L to ppm or are the units interchangeable?

    Many thanks.

    PPM is simply Mg/l divided by the specific gravity. For drinking water(s) the gravity should be 1.000 which makes them the same.

    I think you mean ppg...

    ppm = parts per million, and it is the same as mg/l when it comes to brewing ions like Calcium, Sodium, etc. Gravity does not factor into ppm.
