Ah! I should've kept reading before responding. I submit that a
conversion table indicating that 1 dH KH is approximately 17.9 or so ppm
CO3-- equivalent in alkalinity and don't presume to tell people which they
David W. Webb, who also thinks degrees F is more granular and therefore
better for non-scientific measurements than degrees C and still likes miles
over kilometers because his speedometer is easier to read that way. Which
conveys more meaning? It's 105F in Dallas today or it's 43C?
