Re: KH measurements - what units?

[George Slusarczuk <yurko at warwick_net>]

Hello Joe,

There are two systems of units in common use:

The older German system measures both hardness (GH) and alkalinity (KH)
in "degrees" and the newer, more scientific system that measures the
same parameters in milligrams per liter (mg/L).

The conversion factor is 17.8, i.e. you divide mg/L by 17.8 to get the
(German) degrees.

Best,

George
