need help understanding water test kit units used

[jared.emmanuel]

hi guys i'm currently using sera water test kit . When testing for GH the units expressed in dGH. This is were i'm a bit confused here's an example if someone tells me to adjust my GH to get a reading of say 3 GH but now my test kit is given in degrees of hardness , is there a difference/ conversion i need to do? I'm confused if 3 GH is expressed in ppm or mg/l . Really need some help understanding this :confused:

Easy way. multiplying your dh by 17 will give you ppm.
