hi there can anyone tell me why im working in different formule with chemicals in water please i see all you guys work in PPM particularly with nitrates, but i work with MG/L are these different values or just different ways of writing the same calculus
e.g....is 5ppm....the same as....5mg/l and if not is there a conversion table for these measures please as all my tests are done using the MG/L formale i guess they are the same as........ MILIgrammes and LITRE and PART per MILLION
seem to match pretty well if you think about it but i would like confirmation from someone who knows for sure please ..thanks to all who help............. and all who dont.

Yes the same:)
