11/15/2023 0 Comments 50 kw to ampKnowing these two numbers, you can now calculate your battery capacity in amp hours. You look through the product manual and find that the battery voltage is 43.2 volts. Let's say you own a solar generator with a battery capacity of 2.16 kilowatt hours. To convert kilowatt hours to amp hours, divide kilowatt hours by volts, then multiply by 1,000.Ĭonversion formula: amp hours = kilowatt hours ÷ volts × 1000Ībbreviated: Ah = kWh ÷ V × 1000 Example: How to Calculate Amp Hours of a Battery How to Convert Kilowatt Hours to Amp Hours (kWh to Ah) Note: Don't see the values you're looking for in this chart? Use our kilowatt hours to amp hours conversion calculator at the top of this page to calculate them for your specific scenario. Here is a conversion chart converting common kilowatt hour values to amp hours at 12V and 24V. Current (Amps)Įquivalent Amps and Kilowatts at 240V AC Equivalent ampere and kilowatt values at 240 volts.Or would you instead like to convert amp hours to kilowatt hours? Kilowatt Hours to Amp Hours Conversion Chart You might also be interested in our amps to watts calculator.Įquivalent Amps and Kilowatts at 120V AC Equivalent ampere and kilowatt values at 120 volts. Thus, the power P in kilowatts is equal to the current I in amps squared multiplied by the resistance R in ohms, divided by 1,000. It’s also possible to convert amps to kilowatts using circuit resistance with this formula: How to Convert Amps and Ohms to Kilowatts This formula is correct for the power delivered by all three wires in the three-phase system, but if you’re considering one wire in the three-phase system, you’ll need to divide by three. Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts multiplied by the power factor PF multiplied by 3, divided by 1,000. The formula to convert amps to kilowatts for three-phase AC circuits where the line to neutral RMS voltage is known is: This equation is correct when considering one pair of wires in the three-phase system, but when considering all three pairs of wires in the three-phase system, you would need to multiply it by three. Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts multiplied by the power factor PF multiplied by the square root of 3, divided by 1,000. The formula to convert amps to kilowatts for three-phase AC circuits where the current, line to line RMS voltage, and power factor is known is: Three-Phase AC Circuit Amps to Kilowatts Conversion Using Line to Line Voltage Try our power factor calculator to get the power factor if needed. Thus, the real power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts multiplied by the power factor PF, divided by 1,000. The PF is a property determined by the AC frequency and the amount of inductive or capacitive elements in the circuit. The magnitude of both real and reactive together is called the apparent power, and the PF gives the ratio of real power to apparent power. P (kW) = 1.44 kW Single-Phase AC Circuit Amps to Kilowatts ConversionĬonversion of amps to kilowatts for single-phase alternating current (AC) circuits using the current, RMS voltage, and power factor (PF) can be done with a slightly different formula.ĪC electrical power is composed of a real part, expressed in watts (W), and a reactive part, expressed in volt-amps (VA). For example, let’s find the kilowatts of power for a circuit with 12 amps of current at 120 volts.
