Using the same example from earlier, the same oven would be 1,000 watts divided by 500 volts, equaling 2 amps. To obtain the amps of a circuit you’ll divide the watts by the volts. Calculating a circuit’s amps is the reverse of getting its wattage. Higher amp values equate to higher current, as one might expect. Using the same calculation it would come out to 1,000 watts or 1 kilowatt.Īmperes, or amps, describe the flow of current through a circuit. As just a basic example, let’s say you have an oven that draws 500 volts at 2 amperes. Kilowatts are derived from multiplying the voltage of a circuit against the amperes of a circuit to get the final product. If you have any sort of power tool, appliance, and so on, they will be measuring the store of power as a watt or kilowatt. What They MeasureĪ kilowatt is 1,000 watts. It along with the ohm are the two first widely accepted standards utilized in electrical work. Amperes were standardized as a unit of measurement by the International Electrical Congress, in 1893, with widespread international acceptance occurring in 1908. Its discovery was a crucial first step in understanding how to implement electricity for practical applications. Ampere, the scientist not the measurement mind you, did instrumental work in discovering the existence of the electron. Since its standardization, it has been ubiquitous in its usage for electrical applications.Īndre Marie Ampere serves as the namesake of the ampere. The watt became a standard unit of measurement thanks to the SI in 1960 at the 11th General Conference on Weights and Measures. It has very little in common with the work done by Watt himself, who is responsible for the separate condenser and parallel motion components of the steam engine. The watt gets its name from James Watt, an 18th-century British inventor. As with many of the other units of measurement common in electricity, their names from real-world scientists with instrumental contributions to the progress of technology. What are Kilowatts and Amps?īoth the kilowatt and amp are units of measure for electricity. They are very starkly different units of measurement, however, with entirely different purposes. With most units of measurement in electricity, there is some overlap, and these are no different. It is important to note that these two measurements go hand in hand with each other. The rate at which power is consumed by a load These units of measurement are very common in electrical applications and this can help to dispel whatever misconceptions you may have regarding their usage. With today’s guide, let’s take a closer look at the difference between kilowatts and amperes, or amps. There are many different possible units of measurement, and they all have various applications. In particular, this comes down to the many units of measurement present for electricity. For those starting to venture into electricity, however, there is a fair bit of knowledge to absorb. Its usage enables much of what makes the modern world possible and powers everything from humble light bulbs to magnificently complex computers. Electricity is one of the true marvels of modern history.
