About Converting Megawatts to Picowatts
Megawatt and Picowatt both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Megawatt is 1000000 watt units, and picowatt is 1e-12 watt units.
Formula
picowatts = megawatts × 1e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 megawatt equals 1000000 base units, and 1 picowatt equals 1e-12 base units, so dividing one by the other gives the direct megawatt-to-picowatt factor of 1e+18.
Simple example
1 MW × 1e+18 = 1e+18 pW
1 megawatt = 1e+18 picowatts.
Real-world example
120 MW × 1e+18 = 1.2e+20 pW
120 megawatts = 1.2e+20 picowatts.

Reverse conversion: Picowatt to Megawatt
1e+18 pW × 1e-18 = 1 MW
1e+18 picowatts = 1 megawatt.
megawatts = picowatts × 1e-18

Frequently asked questions
How many picowatts are in 1 megawatt?
1 megawatt equals 1e+18 picowatts, using the exact defined conversion factor rather than an estimate.
How do I convert megawatt to picowatt?
Multiply the megawatt value by 1e+18. The converter above does this instantly to whatever precision you set.
How do I convert picowatt back to megawatt?
Use the reverse factor: 1 picowatt equals 1e-18 megawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a megawatt?
Megawatt (MW) is a unit of electricity.
What is a picowatt?
Picowatt (pW) is a unit of electricity.
Is the megawatt to picowatt conversion exact?
Yes. Both megawatt and picowatt are defined by fixed standards rather than physical artifacts, so the factor of 1e+18 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
