500 mA is equal to 0.5 amps. The term “mA” denotes milliamp. In the metric system, amp (A) or ampere is the unit measurement for electric current.Continue Reading
To make this calculation, one has to know the conversion equivalents between these two units. The relationship states that 1 amp is equal to 1 milliamp divided by 1000 milliamps per amp, or A = mA/1000. From this relationship, one can substitute 500 for mA, or 500/1000 that also is 0.5. This is equal to the number of amps.
Converting from amps to milliamps, one can use the equation milliamp = 1000 milliamps per amp x amp, or mA = 1000 x A. If one substitutes 0.5 amp for A into this equation, one finds that mA= 1000 x 0.5 = 500.Learn more about Measurements
Amps are a measure of electric current and kilowatts are a measure of electric power, so the two are not strictly interchangeable. This means that a third factor, voltage, must be accounted for in any conversion of amps to kilowatts.Full Answer >
In general, watts are calculated by taking the current, in amps, and multiplying by the voltage. AC currents involve additional steps, which may include multiplying by a power factor (for single-phase currents) or multiplying by a power factor and a coefficient (for three-phase currents).Full Answer >
Converting kilowatts to amps first requires knowledge of the current type, whether it is DC, AC single phase or AC three phase, as each calculation differs. Additionally, the voltage in volts must also be known for all three calculations.Full Answer >
The simplest conversion formula to convert watts to amps is based on the formula for amps, which is power (in Watts) divided by Volts. This is written as I(Amps) = P(Watts) / V(Volts). By simply rearranging this formula, it is easy to convert amps to watts and vice versa.Full Answer >
