Simply times (x) EC (μS/cm) by .55 to get an approximate ppm equivalent. To convert TDS - ppm back to EC units you divide the ppm value by .55. ppm can be thought of as the same as mg/l. 1 (gpg, grains per gallon) = approximately *14 ppm * a less common unit, but used occasionally

Conversion of units of measurement from physics and maths, e.g. Conductivity - Microsiemens per metre [µS/m]

If your water is too saline, it can affect your plants  in microsiemens (µS/cm) or millisiemens (mS/cm), while others use readings that have been converted to TDS, which are expressed in parts per million (ppm)   Often the literature will use microSiemens (uS/cm) and EC standing for electrical conductivity. These two units are the same. To convert milliSiemens (mS) to  Other than this, 570 micro Siemens theoretically gives us a TDS (total dissolved solids) ppm of 365. So the measurement a scientific EC meter has given us is  Sep 5, 2013 Microsiemens isn't really a good substitute for ppm . It doesn't convert well between units, unfortunately. Here's some reading on the topic.

Water > 80 ppm CaCO3 is often treated with water softeners which adds salts to the nutrient. If hard water is suspected, contact the water department & obtain the annual water quality report. Useful information on the report includes ppm calcium carbonate (CaCO3, Mg, Ca, & Na & pH. Sometimes it is useful to have some sort of comparison for values measured on a conductivity meter. Remember that conductivity of seawater is around 54000 µS/cm. This is approximately 35000 ppm TDS. Seawater has a high proportion of sodium chloride and this is around 28000 ppm.

100 microsiemens to millisiemens = 0.1 millisiemens.

ppm and ppb are defined as: 1ppm = 1/10 6 = 10-6. 1ppb = 1/10 9 = 10-9. So. 1ppm = 1000ppb. The number of parts-per million x ppm is equal to the number of parts-per billion x ppb divided by 1000: Microsiemens Conversion Factors - Conductance All Conductance Conversion Tables abmho gemmho kilosiemens megasiemens mho micromho microsiemens millisiemens siemens statmho ppm TDS: Siemens (S) is de eenheid van geleiding.
