Conversion

dKH to meq/L (alkalinity)

Convert between dKH and meq/L for alkalinity. Hobby test kits report dKH; chemistry literature uses meq/L. Same parameter, different scale.

Formula

meq/L  =  dKH × 0.3566

dKH  =  meq/L × 2.804

Quick reference

dKH	meq/L
6	2.14
7	2.496
8	2.853
9	3.209
10	3.566
11	3.923
12	4.279
