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.
Conversion Formulas
DC Circuit Calculation
Where:
- P = Power in Megawatts
- I = Current in Amps
- V = Voltage in Volts
AC Single Phase Calculation
Where:
- PF = Power Factor
- I = Current in Amps
- V = RMS Voltage in Volts
AC Three Phase Calculation
Line to Line:
P(MW) = (√3 × PF × I(A) × VL-L(V)) / 1,000,000Line to Neutral:
P(MW) = (3 × PF × I(A) × VL-N(V)) / 1,000,000Typical Power Factor Values

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) × 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.
