Select the same unit in both menus to keep the numerical value unchanged, apart from any display rounding.<\/p>\n<h2>What electrical resistivity means<\/h2>\n<p>Electrical resistivity, represented by \\(\\rho\\), describes how strongly a material opposes electric current. A lower resistivity generally means a material is a better electrical conductor. Resistivity is a material property, whereas the resistance of a particular piece also depends on its dimensions. For a uniform conductor, \\(R=\\rho L\/A\\), where \\(R\\) is resistance, \\(L\\) is length, and \\(A\\) is cross-sectional area.<\/p>\n<p>The SI unit is the ohm meter (\u03a9\u00b7m). Smaller units are often more convenient when reporting metals: the default value, representative of copper near room temperature, is 1.68 \u03bc\u03a9\u00b7cm. \u03a9\u00b7cm is also used for materials with higher resistivity, while \u03a9\u00b7mm\u00b2\/m is convenient in wire calculations because length may be measured in meters and cross-sectional area in square millimeters. Changing units changes only the number used to express a resistivity, not the underlying material property.<\/p>\n<p>Resistivity should not be confused with conductivity, its reciprocal, or with conductance, the reciprocal of a component\u2019s resistance. If you are comparing component measurements rather than material properties, the <a href=\"https:\/\/wpcalc.com\/en\/converters\/conductance\/\">Conductance Units converter<\/a> may be more appropriate. For measurements expressed as current, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/electric-current\/\">Electric Current converter<\/a>.<\/p>\n<h2>Unit factors and practical limits<\/h2>\n<p>For the four SI-derived units, the converter uses these factors to express one unit in \u03a9\u00b7m:<\/p>\n<table>\n<thead>\n<tr>\n<th>Unit<\/th>\n<th>1 unit equals<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>\u03a9\u00b7m<\/td>\n<td>1 \u03a9\u00b7m<\/td>\n<\/tr>\n<tr>\n<td>\u03a9\u00b7cm<\/td>\n<td>0.01 \u03a9\u00b7m<\/td>\n<\/tr>\n<tr>\n<td>\u03bc\u03a9\u00b7cm<\/td>\n<td>\\(10^{-8}\\) \u03a9\u00b7m<\/td>\n<\/tr>\n<tr>\n<td>\u03a9\u00b7mm\u00b2\/m<\/td>\n<td>\\(10^{-6}\\) \u03a9\u00b7m<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These factors provide quick checks: 1 \u03a9\u00b7m is 100 \u03a9\u00b7cm, \\(10^8\\) \u03bc\u03a9\u00b7cm, or \\(10^6\\) \u03a9\u00b7mm\u00b2\/m. When comparing published values, check that they refer to the same temperature and material condition. Resistivity often changes with temperature, and this converter performs no temperature correction.<\/p>\n<p><strong>Important CGS limitation:<\/strong> The calculator uses \\(1\\ \\mathrm{stat\\Omega\\cdot cm}=8.98755179\\times10^{11}\\ \\Omega\\cdot\\mathrm{m}\\). The physical conversion is approximately \\(8.98755179\\times10^9\\ \\Omega\\cdot\\mathrm{m}\\). Consequently, conversions involving stat\u03a9\u00b7cm differ from the physical conversion by a factor of 100. Avoid using its stat\u03a9\u00b7cm results for scientific or engineering work unless that factor is corrected.<\/p>\n<p>The displayed result is rounded to 12 decimal places. Extremely small nonzero results may therefore appear as zero; if that happens, convert through a smaller unit or calculate with the factors above.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Convert electrical resistivity between \u03a9\u00b7m, \u03a9\u00b7cm, \u03bc\u03a9\u00b7cm, \u03a9\u00b7mm\u00b2\/m, and stat\u03a9\u00b7cm.
