### Amps to VAR, kVAR and MVAR Calculator:

Enter the current in amps, the voltage in volts and the power factor, and choose the Value you need to find VAR or kVAR or MVAR, then press the calculate button to get the results.

### Convert Amps to VAR

Electrical current is measured by using Amps unit and reactive power is measured by VAR unit. Hence for calculating reactive power in VAR from amps, the reactive power Q_{(VAR)} in VAR is equal to the product of line current I_{(A)} in Amps times of line voltage V_{(V)} and sine of power angle sin(φ).

Amps to VAR Calculation formula,

Q_{(VAR)} = V_{(V)} x I_{(A)} x sin(φ)

For three-phase with line voltage V_{(L-V)},

Q_{(VAR)} = 1.732 x V_{(L-V)} x I_{(A)} x sin(φ)

For three-phase with phase voltage V_{(P-V)},

Q_{(VAR)} = 3 x V_{(P-V)} x I_{(A)} x sin(φ)

### Convert Amps to kVAR:

Reactive power Q_{(kVAR)} in Kilo Volt Amp reactive is equal to the 0.001 times of line current I_{(A)} in amps and the line voltage V_{(V)} (For three-phase, you have to consider 1.732 times of the Line voltage) and the sine of power angle.

Power angle can be calculated from the power factor by using cos^{-1}(pf)

Amps to kVAR calculation formula,

Q_{(kVAR)} = V_{(V)} x I_{(A)} x sin(φ) / 1000

For three-phase with line voltage V_{(L-V)},

Q_{(kVAR)} = 1.732 x V_{(L-V)} x I_{(A)} x sin(φ) / 1000

For three-phase with phase voltage V_{(P-V)},

Q_{(kVAR)} = 3 x V_{(P-V)} x I_{(A)} x sin(φ) / 1000

### Convert Amps to MVAR:

MVAR is the very largest unit of reactive power and which is used in transmission line reactive power management. The mega volt-ampere reactive is equal to line current I_{(A)} in Amps times of voltage V_{(V)} in volts and the sine of power angle(φ) divided by the 1,000,000. Hence the formula can be written as,

Amps to MVAR calculation formula,

Q_{(MVAR)} = V_{(V)} x I_{(A)} x sin(φ) / 1000000

For three-phase with line voltage V_{(L-V)},

Q_{(MVAR)} = 1.732x V_{(L-V)} x I_{(A)} x sin(φ) / 1000000

For three-phase with phase voltage V_{(P-V)},

Q_{(MVAR)} = 3 x V_{(P-V)} x I_{(A)} x sin(φ) / 1000000
