The result includes the selected destination unit and is rounded to six decimal places.<\/li>\n<\/ol>\n<p>The available units are volts per meter (V\/m), kilovolts per meter (kV\/m), newtons per coulomb (N\/C), volts per centimeter (V\/cm), and statvolts per centimeter (statV\/cm). If you choose the same unit in both menus, the numerical value stays the same, subject to the displayed rounding.<\/p>\n<h2>What electric field strength means<\/h2>\n<p>Electric field strength describes the force that an electric field would exert per unit of positive test charge at a point. Its SI unit is the newton per coulomb (N\/C). It can also be expressed in volts per meter (V\/m): 1 N\/C is exactly 1 V\/m. The two units describe the same quantity from force-per-charge and potential-gradient perspectives.<\/p>\n<p>In a uniform field, such as the idealized field between parallel plates, field strength is the voltage difference divided by the separation in meters. For example, 100 V across a 0.01 m gap gives 10,000 V\/m, or 10 kV\/m. This simple relationship is useful for estimating a field, but an actual field may vary with position, especially near edges or irregularly shaped electrodes.<\/p>\n<p>Changing units does not change the physical field. For instance, 1 V\/cm equals 100 V\/m, while 1 kV\/m equals 1,000 V\/m. Choosing a convenient unit makes it easier to compare measurements, specifications, or calculations without carrying unnecessarily large or small numbers. Electric fields are distinct from <a href=\"https:\/\/wpcalc.com\/en\/converters\/magnetic-flux-density\/\">magnetic flux density<\/a>, even though the two are often discussed together in electromagnetism.<\/p>\n<h2>Conversion factors and important limitations<\/h2>\n<p>The table shows how many V\/m correspond to one unit. These factors are also the ones used by the calculator, except that its statV\/cm factor differs from the physically correct conversion.<\/p>\n<table>\n<thead>\n<tr>\n<th>Unit<\/th>\n<th>V\/m per unit<\/th>\n<th>Calculator status<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>V\/m<\/td>\n<td>1<\/td>\n<td>Correct<\/td>\n<\/tr>\n<tr>\n<td>kV\/m<\/td>\n<td>1,000<\/td>\n<td>Correct<\/td>\n<\/tr>\n<tr>\n<td>N\/C<\/td>\n<td>1<\/td>\n<td>Correct<\/td>\n<\/tr>\n<tr>\n<td>V\/cm<\/td>\n<td>100<\/td>\n<td>Correct<\/td>\n<\/tr>\n<tr>\n<td>statV\/cm<\/td>\n<td>Approximately 29,979.2458<\/td>\n<td>Uses 299.792458 instead<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>Do not rely on results involving statV\/cm.<\/strong> One statvolt is approximately 299.792458 volts, but one centimeter is 0.01 meter. Therefore, 1 statV\/cm is approximately 29,979.2458 V\/m, not 299.792458 V\/m. The calculator\u2019s factor is 100 times too small: conversions from statV\/cm to other units produce results 100 times too small, and conversions into statV\/cm produce results 100 times too large. Conversions that use only V\/m, kV\/m, N\/C, and V\/cm are unaffected.<\/p>\n<p>This tool converts field-strength units; it does not calculate a field from voltage, charge, or geometry. The input accepts nonnegative values only, so it cannot represent a signed field component or direction. Very small converted values may display as zero because results are rounded to six decimal places. Keep direction and measurement conditions separately when comparing fields. If your wider calculation involves moving charge or magnetic effects, the <a href=\"https:\/\/wpcalc.com\/en\/converters\/electric-current\/\">electric current converter<\/a> and <a href=\"https:\/\/wpcalc.com\/en\/converters\/magnetic-flux\/\">magnetic flux converter<\/a> handle those different quantities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Convert electric field strength between V\/m, kV\/m, N\/C, V\/cm, and statV\/cm.
