ppm to dGh?

[Morganna]

Hello! So, my test strips read in ppm, but all the websites I look at when l do research on fish give the GH and KH in the dGH and dKH form.
Can anyone advise on how to swap one on to the other?
Hope that made sense, because I kinda questioned my wording choices.
Thanks!

I too would like to know this.

You can use the aquarium calculator at the link below. It is found on the right side of the page under Useful Links.

Or

1 dGH = 17.9ppm
1 dKH = 17.9ppm

You can also multiply/divide on your own, which some may find faster. Divide ppm by 17.9, or multiply dH by 17.9 and this works for GH and KH.
