You can change either unit to compare another conversion.<\/li>\n<\/ol>\n<p>The available choices are volts per meter (V\/m), kilovolts per meter (kV\/m), newtons per coulomb (N\/C), statvolts per centimeter (statV\/cm), and volts per centimeter (V\/cm). For physically reliable conversions, use the V\/m, kV\/m, N\/C, and V\/cm choices. The calculator\u2019s statV\/cm conversions have a known factor error.<\/p>\n<h2>What electric field strength means<\/h2>\n<p>Electric field strength describes the electric force that a charged object would experience at a location, per unit of charge. Its SI unit, the newton per coulomb (N\/C), follows from that definition. The volt per meter (V\/m) is an equivalent SI unit: \\(1\\,\\mathrm{N\/C}=1\\,\\mathrm{V\/m}\\). You can therefore switch between N\/C and V\/m without changing the numerical value.<\/p>\n<p>Volts per meter also describe the potential difference per distance in a uniform field. For example, a field of 1,000 V\/m corresponds to a potential change of 1,000 V across one meter in the field\u2019s direction. The same strength can be written as 1 kV\/m or 10 V\/cm. Choosing a unit that suits the scale of a problem can make the result easier to read without changing the field itself.<\/p>\n<p>Electric field strength is not electric current. Current measures the rate at which charge flows and is expressed in amperes; this calculator neither accepts nor converts amperes. It also does not calculate the force on a particular charge. If you know the charge and need that force, the relationship is \\(F=qE\\); the resulting force can be converted with the <a href=\"https:\/\/wpcalc.com\/en\/converters\/force\/\">Force converter<\/a>.<\/p>\n<h2>Conversion reference<\/h2>\n<table>\n<thead>\n<tr>\n<th>Unit<\/th>\n<th>Equivalent in V\/m<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1 V\/m<\/td>\n<td>1 V\/m<\/td>\n<\/tr>\n<tr>\n<td>1 N\/C<\/td>\n<td>1 V\/m<\/td>\n<\/tr>\n<tr>\n<td>1 kV\/m<\/td>\n<td>1,000 V\/m<\/td>\n<\/tr>\n<tr>\n<td>1 V\/cm<\/td>\n<td>100 V\/m<\/td>\n<\/tr>\n<tr>\n<td>1 statV\/cm<\/td>\n<td>Approximately 29,979.2458 V\/m physically; the calculator uses 299.792458 V\/m<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The first four rows can be used as a quick check on a result. For instance, converting from V\/cm to V\/m multiplies the number by 100 because a meter contains 100 centimeters. Converting back divides it by 100. The statV\/cm row shows both the physical equivalence and the different factor currently used by the calculator; they should not be treated as interchangeable.<\/p>\n<h2>Assumptions and limitations<\/h2>\n<p><strong>Do not rely on the statV\/cm result for a physical conversion.<\/strong> One statvolt is approximately 299.792458 volts, but one centimeter is 0.01 meter. Thus, \\(1\\,\\mathrm{statV\/cm}\\approx29{,}979.2458\\,\\mathrm{V\/m}\\), not 299.792458 V\/m. The calculator omits the additional factor of 100: converting <em>from<\/em> statV\/cm produces a value 100 times too small, while converting <em>to<\/em> statV\/cm produces a value 100 times too large. Use the physical equivalence above for work involving that unit.<\/p>\n<p>The input accepts only nonnegative values, so it represents field magnitude rather than a signed component or a full vector direction. Converting units cannot determine the field around a particular object or account for changes across space. The displayed result is rounded to six decimal places; very small nonzero results may therefore appear as zero. Keep more precision in intermediate work when that matters.<\/p>\n<p>An electric field and a magnetic field are different quantities, even when both appear in the same problem. For magnetic-field units, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/magnetic-flux-density\/\">Magnetic Flux Density converter<\/a> rather than treating those units as electric field units.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Convert electric field strength between V\/m, kV\/m, N\/C, V\/cm, and statV\/cm.
