The watt unit is named after James Watt, the inventor of the steam engine and ampere is named after AndrÃ©-Marie AmpÃ¨re, a French mathematician and physicist. kW To Amps Calculator. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on. Generator Sizing Calculator. 1 Ampere is defined as the electrical current that flows with electric charge of one Coulomb per second. In terms of the hosepipe example, this would refer to the amount of water being released. Watts To Amps Calculator (W to A) Here you can easily convert watts to amps using this calculator: Input Watts (W) Input Volts (V) 0.00 Amps. P (W) = PF × I (A) × V (V). Amps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. DC watts to amps calcu Current (A) = Voltage (V) ÷ Resistance (Ω) For example, let’s find the current of a 12 volt circuit with 10 ohms of resistance. Calculating volts to amps with watts If you select this option as your calculation, you need to enter the correct values of the volts and the watts in their respective fields. amps = volts ÷ ohms amps = 12 V ÷ 10 Ω amps = 1.2 A. HOWEVER, if you have at least least two of the following three: amps, volts or watts then the missing one can be calculated. P (W) = I (A) × V (V). Example 2: Must calculate the ampere-hours of a battery to have 100 watt-hour capacity at 7.2 volts: View example: Example 3: Must calculate the voltage of a battery having 80mAh and 288mWh: View example : Voltage: V: Ampere-hours: Ah: Watt-hours: Wh: You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga. Watt is an SI unit of electric power and is denoted by 'W'. It can either be direct current (DC) or alternating current (AC). Please share. Please help me spread the word by sharing this with friends or on your website/blog. Such resources typically ask you to enter the number of volts, and the number of amps. Watts: Amps and volts combine to create watts, a measurement of the amount of energy being released. For AC power supply, amps are equal to watts divided by power factor times volts. Ampere is the SI unit of electric current represented as 'A'. The Amps to Watts Converter has two active buttons which allow you to carry out the calculation. Basics. kW to Amps – Conversion, formula, chart, convert and calculator free. The first step is to select the current type. For example, the more wattage a microwave has to offer, the faster it will cook your food. Then you are asked to hit the “calculate” button to get the watts. Ohms to Amps calculation with watts. Formula is (Ah)*(V) = (Wh). Amps to Watts Calculator. The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V):. Convert Watt hour to Amp hour (Wh to Ah) Insert Watts-hour (Wh) and voltage (V) below and click on Calculate to obtain Amp-hours (Ah). Ampere (amps or amperage) is an SI unit of electric current and is denoted by 'A'. It is a unit of electric current equal to a flow of one coulomb per second. AC three phase Amps to watts calculation Line to line voltage. You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). Enter the power in watts (W), voltage in volts (V), select power factor (PF) from 0 to 1 with a 0.1 step (for AC), then press the Calculate button to get the result in amps (A). You can calculate (but not convert) the amps from watts and volts: Amps calculation with voltage of 12V DC. amps = 1000W / 12V = 83.333A . Kilowatts to amps Calculator (kW to A): Using our kW to Amp calculator, you can convert DC, Single phase and three phase kilo Watts to Ampere Online. Calculate amps. Power in watts (W) Current in amps (A) R (Ω) = P (W) / I (A) 2. Finance ; Math; Science and Engineering; Health & Fitness; Other; x. Watts = AMPs x Volts (W= A x V)This formula can also be written as Power=AMPs x Volts (P= A x V). KD Calculator; Steps to Calories Calculator; Resultant Force Calculator; Population Growth Calculator; Maturity Value Calculator; Categories. In the end, you will also find a watts-to-amps table at 120V electric potential . I = [kW * 1000] / [E * PF] Example: A 120-volt single phase AC circuit has 20 kW load. Conversion charts, are available further down the page. DC amps to watts calculation.
