The nanowatt conversion selector here selects the power measurement unit to convert to starting from nanowatts (nW). To make a conversion starting from a unit of power other than nanowatt, simply click on the "Reset" button.
The nanowatt is a unit of power equal to 10-9 watts (1 nW = 10-9 W), the derived unit of power in the International System of Units (SI).
The nanowatt (nW) is also equal to 10-6 milliwatts (mW), or 0.001 microwatts (μW), or 10-12 kilowatts (kW), or 10-15 megawatts (MW), or 10-18 gigawatts (GW) or 10-21 terawatts (TW).
1 nW = 10-9 W = 10-9 J/s = 10-9 N×m/s = 10-9 kg×m2/s3
