The picowatt (pW), not to be confused with the much larger petawatt (PW), is equal to one trillionth (10−12) of a watt. Technologically important powers that are measured in picowatts are typically used in reference to radio and radar receivers, acoustics and in the science of radio astronomy.
| 1 picowatts = 1.0E-18 megawatts | 6 picowatts = 6.0E-18 megawatts |
| 2 picowatts = 2.0E-18 megawatts | 7 picowatts = 7.0E-18 megawatts |
| 3 picowatts = 3.0E-18 megawatts | 8 picowatts = 8.0E-18 megawatts |
| 4 picowatts = 4.0E-18 megawatts | 9 picowatts = 9.0E-18 megawatts |
| 5 picowatts = 5.0E-18 megawatts | 10 picowatts = 1.0E-17 megawatts |
The megawatt (MW) is equal to one million (106) watts. Many events or machines produce or sustain the conversion of energy on this scale, including large electric motors; large warships such as aircraft carriers, cruisers, and submarines; large server farms or data centers; and some scientific research equipment, such as supercolliders, and the output pulses of very large lasers. A large residential or commercial building may use several megawatts in electric power and heat. On railways, modern high-powered electric locomotives typically have a peak power output of 5 or 6 MW, although some produce much more. The Eurostar, for example, uses more than 12 MW, while heavy diesel-electric locomotives typically produce/use 3 to 5 MW. U.S. nuclear power plants have net summer capacities between about 500 and 1300 MW.
