The terawatt is a unit of power equal to 1012 watts (1 TW = 1012 W), the derived unit of power in the International System of Units (SI).
The terawatt (TW) is also equal to 1015 milliwatts (mW), or 1018 microwatts (μW), or 109 kilowatts (kW), or 1,000,000 megawatts (MW) or 1,000 gigawatts (GW).
1 TW = 1012 W = 1012 J/s = 1012 N×m/s = 1012 kg×m2/s3
