Sorry for the link but this is probably the most helpful explanation I've seen around



If this doesn't help, you should go to the manufacture website - they usually have instructions that gives the conversion.

So my bluelab tells me that an EC of 0.7 equates to a CF of 7 a TDS of 350 and a ppm of 490....I don't know what your meter is but maybe that can help you?
