How to convert conductivity to resistivity?

Electrical resistivity (ER) is reciprocal to conductivity (EC) and results can be easily recalculated using formula EC=1/ER or vice versa ER=1/EC. Electrical resistivity is more convenient to use on non-saline soils, where conductivity can be mSm/m, while resitivity measures in 102-103 Ohm m range. 1000 Ohm m equals 1 mSm/m. You can find more conversions to ppm, TDS, grains of salt in this flyer.
