Charts to convert ppm/EC/CF

One of the problems with conversing with Growers in different areas and with different equipment is that CF/ppm/EC meters will express different yet very similar measurements all effectively say the same exact thing it's just a case of what measurement you use

The two levels expressed at either end of the columns are the generic measurements of CF and EC and the center 3 columns express the different PPM equivalents for the 3 most popular meters used internationally
