dH to gH?

[DARK Jak]

well you see I got a water tester for all sorts of things but the problem is it has gH and all my calculations are in dH I didnt know if they are two completly different things or just another way of messuring hardness.
If anyone know I need to figure out what 14 dH would be in gH
TIA

multiply by, uhm..... 17.9? Yeah. 17.9. So thats 250

Just to clarify here: there are two major methods for reporting water hardness; german degress, and ppm (or mg/l..they are interchangable)

As Tom says, to convert degrees to a ppm value, multiply by 17.9. To go from ppm to degrees, divide by 17.9.


To further confuse you, sometimes carbonate hardness tests read in meq/l.
