Use the unit that matches the number you have.<\/li>\n<li>Under <strong>From unit<\/strong>, select Siemens (S), Millisiemens (mS), Microsiemens (\u00b5S), or Nanosiemens (nS).<\/li>\n<li>Under <strong>To unit<\/strong>, select the unit you want for the answer.<\/li>\n<li>Read <strong>Converted Conductance Value<\/strong>. The result includes the selected output unit.<\/li>\n<\/ol>\n<p>For example, to express 250 \u00b5S in mS, enter 250, choose Microsiemens (\u00b5S) as the From unit, and choose Millisiemens (mS) as the To unit. The result is 0.25 mS. You can also select the same unit in both menus to leave the value unchanged.<\/p>\n<h2>What conductance means<\/h2>\n<p>Electrical conductance describes how readily current passes through a particular component or path. Its SI unit is the siemens (S). For a resistance \\(R\\) measured in ohms, conductance is \\(G=1\/R\\), measured in siemens. For instance, a resistance of 1,000 \u03a9 corresponds to a conductance of 0.001 S, or 1 mS. A higher conductance means less opposition to current through that path.<\/p>\n<p>Conductance values often span several orders of magnitude. A circuit measurement might be easier to read as 500 \u00b5S than as 0.0005 S; both describe the same conductance. Converting units does not change the measured property\u2014it only changes the scale used to report it. Check the unit printed beside a measurement before comparing it with a specification or another reading.<\/p>\n<p>Conductance is related to current, but it is not a current measurement. For an ohmic component under suitable conditions, current and voltage satisfy \\(I=GV\\). If you need to express a measured current in different units, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/electric-current\/\">Electric Current Converter<\/a>. Conductance also differs from electrical conductivity: conductivity is a material property, whereas the conductance of a component depends on both its material and its dimensions.<\/p>\n<h2>Unit reference<\/h2>\n<table>\n<thead>\n<tr>\n<th>Unit<\/th>\n<th>Symbol<\/th>\n<th>Equivalent in siemens<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Siemens<\/td>\n<td>S<\/td>\n<td>1 S<\/td>\n<\/tr>\n<tr>\n<td>Millisiemens<\/td>\n<td>mS<\/td>\n<td>0.001 S<\/td>\n<\/tr>\n<tr>\n<td>Microsiemens<\/td>\n<td>\u00b5S<\/td>\n<td>0.000001 S<\/td>\n<\/tr>\n<tr>\n<td>Nanosiemens<\/td>\n<td>nS<\/td>\n<td>0.000000001 S<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Each step down this list makes the unit 1,000 times smaller: 1 S = 1,000 mS, 1 mS = 1,000 \u00b5S, and 1 \u00b5S = 1,000 nS. The symbol \u00b5 is the Greek letter mu, not the letter m; confusing \u00b5S with mS introduces a factor-of-1,000 error.<\/p>\n<h2>Assumptions and practical limits<\/h2>\n<p>This tool converts a stated conductance value; it does not measure a component or calculate conductance from resistance, voltage, current, or physical dimensions. The selectable units are S, mS, \u00b5S, and nS. \u201cMho\u201d and reciprocal ohm (\u03a9\u207b\u00b9) are alternative names or notations for the siemens, but they are not separate selections in the menus.<\/p>\n<p>The displayed result is rounded to six decimal places. A very small nonzero value can therefore appear as zero when converted to a much larger unit. For example, 1 nS is 0.000000001 S, but converting it to S may display 0 S. Choose a smaller output unit, such as nS or \u00b5S, when you need to preserve a small value in the displayed result.<\/p>\n<p>Conductance can change with temperature, operating conditions, or\u2014in an AC circuit\u2014the frequency of the signal. A unit conversion does not account for those changes. Keep the measurement conditions consistent when comparing values. For other frequency-dependent measurements, the <a href=\"https:\/\/wpcalc.com\/en\/converters\/frequency\/\">Frequency Converter<\/a> can help express frequency in the units you need.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Convert electrical conductance between siemens, millisiemens, microsiemens, and nanosiemens.
