TDS / PPM output meter to EC (and CF): conversion ratios
- Thread starter clowntown
- Start date
Its important to note that ALMOST ALL AMERICAN MANUFACTURERS uses the .5 Conversion factor by default (if the meter only measures tds). Which means that HM DIGITAL, HANNA, MILWUAKE, OAKTON, SUNLEAVES etc. uses the .5 factor. Most Euro models uses the .7 conversion factor; i rarley see the .64 conversion factor in use. Hope this helps.
Thanks pontiac for that information! 
If you're in the U.S. and have no idea what the conversion factor is, I suppose it'd be best to assume 0.5 until you know for sure.
Seems now most nutrient manufacturers now differentiate the different PPM conversion factors and also note EC. A couple of examples would be Advanced Nutrients' calculator now displaying EC as well as PPM (and stating the conversion factor) and Canna's calculator giving you an options to display in different conversion factors as well as a "Custom" user-definable one (along with EC of course).
