The greater the length of the material, the lower the resistivity. This means that water samples can be measured quickly and accurately in the field. The resistivity result which is displayed above is in unit ohms∙meter (Ω∙m). //-->. very poorly; it's an insulator. About Lenntech. All can be used to calculate salinity. Salinity Calculator This calculator derives salinity from a value of the in situ conductivity (as determined, for example, by a CTD), temperature and pressure. evaporation of water (lake en pan evaporation) Multimedia (sand) Filtration. Parallel and Series Resistor Calculator The unit of measurement for resistance is Ohms (&ohms;) & for conductance is micro-siemens per centimeter (μS/cm) in SI units. getcalc.com's Resistivity & Conductivity Calculator is an online physics tool to calculate the measure of the resisting or conducting power of a specified material to the flow of an electric current.
