Amps to Megawatts (amp to Mw) Calculator

Amps to Megawatts Calculator

Calculate power (Megawatts) from current (Amps) and voltage for both AC and DC circuits.

Ampere (A)

A unit of electric current measuring the rate of electric charge flow. One ampere equals one coulomb per second.

Megawatt (MW)

A unit of power measuring the rate of energy usage. One megawatt equals one million watts.

DC Circuit Calculation

P(MW) = (I(A) ร— V(V)) / 1,000,000

Where:

  • P = Power in Megawatts
  • I = Current in Amps
  • V = Voltage in Volts

AC Single Phase Calculation

P(MW) = (PF ร— I(A) ร— V(V)) / 1,000,000

Where:

  • PF = Power Factor
  • I = Current in Amps
  • V = RMS Voltage in Volts

AC Three Phase Calculation

Line to Line:

P(MW) = (โˆš3 ร— PF ร— I(A) ร— VL-L(V)) / 1,000,000

Line to Neutral:

P(MW) = (3 ร— PF ร— I(A) ร— VL-N(V)) / 1,000,000

Typical Power Factor Values

Device Typical Power Factor
Resistive Load 1.0
Fluorescent Lamp 0.95
Incandescent Lamp 1.0
Induction Motor (Full Load) 0.85
Induction Motor (No Load) 0.35
Synchronous Motor 0.90

Important: These are typical values. For accurate calculations, use the actual power factor of your device.

FAQs

What is the difference between Amps and Megawatts?

Amps measure the flow of electric current, while Megawatts measure the rate of energy usage on a much larger scale. The relationship between them is defined by the voltage in the circuit.

How do I convert Amps to Megawatts?

To convert Amps to Megawatts, use the formula: P(MW) = (I(A) ร— V(V)) / 1,000,000. You need to know the voltage to perform this calculation.

What is a Power Factor?

The Power Factor (PF) is a measure of how effectively electrical power is being converted into useful work output. It is the ratio of real power (Watts) to apparent power (Volt-Amps).

Why is the Power Factor important?

A low power factor indicates poor efficiency, which can lead to higher energy costs and potential penalties from utility companies.
