About Converting Terawatts to Microwatts
Terawatt and Microwatt 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: Terawatt is 1000000000000 watt units, and microwatt is 0.000001 watt units.
Formula
microwatts = terawatts × 1e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 terawatt equals 1e+12 base units, and 1 microwatt equals 0.000001 base units, so dividing one by the other gives the direct terawatt-to-microwatt factor of 1e+18.
Simple example
1 TW × 1e+18 = 1e+18 uW
1 terawatt = 1e+18 microwatts.
Real-world example
120 TW × 1e+18 = 1.2e+20 uW
120 terawatts = 1.2e+20 microwatts.

Reverse conversion: Microwatt to Terawatt
1e+18 uW × 1e-18 = 1 TW
1e+18 microwatts = 1 terawatt.
terawatts = microwatts × 1e-18

Frequently asked questions
How many microwatts are in 1 terawatt?
1 terawatt equals 1e+18 microwatts, using the exact defined conversion factor rather than an estimate.
How do I convert terawatt to microwatt?
Multiply the terawatt value by 1e+18. The converter above does this instantly to whatever precision you set.
How do I convert microwatt back to terawatt?
Use the reverse factor: 1 microwatt equals 1e-18 terawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a terawatt?
Terawatt (TW) is a unit of electricity.
What is a microwatt?
Microwatt (uW) is a unit of electricity.
Is the terawatt to microwatt conversion exact?
Yes. Both terawatt and microwatt 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.
