About Converting Microwatts to Megawatts
Microwatt and Megawatt 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: Microwatt is 0.000001 watt units, and megawatt is 1000000 watt units.
Formula
megawatts = microwatts × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 microwatt equals 0.000001 base units, and 1 megawatt equals 1000000 base units, so dividing one by the other gives the direct microwatt-to-megawatt factor of 1e-12.
Simple example
1 uW × 1e-12 = 1e-12 MW
1 microwatt = 1e-12 megawatts.
Real-world example
120 uW × 1e-12 = 1.2e-10 MW
120 microwatts = 1.2e-10 megawatts.
Conversion table

Reverse conversion: Megawatt to Microwatt
1e-12 MW × 1e+12 = 1 uW
1e-12 megawatts = 1 microwatt.
microwatts = megawatts × 1e+12

Frequently asked questions
How many megawatts are in 1 microwatt?
1 microwatt equals 1e-12 megawatts, using the exact defined conversion factor rather than an estimate.
How do I convert microwatt to megawatt?
Multiply the microwatt value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert megawatt back to microwatt?
Use the reverse factor: 1 megawatt equals 1e+12 microwatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a microwatt?
Microwatt (uW) is a unit of electricity.
What is a megawatt?
Megawatt (MW) is a unit of electricity.
Is the microwatt to megawatt conversion exact?
Yes. Both microwatt and megawatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-12 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.
