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 = 1000 femtowatts | 6 picowatts = 6000 femtowatts |
2 picowatts = 2000 femtowatts | 7 picowatts = 7000 femtowatts |
3 picowatts = 3000 femtowatts | 8 picowatts = 8000 femtowatts |
4 picowatts = 4000 femtowatts | 9 picowatts = 9000 femtowatts |
5 picowatts = 5000 femtowatts | 10 picowatts = 10000 femtowatts |
The femtowatt (fW) is equal to one quadrillionth (10−15) of a watt. Technologically important powers that are measured in femtowatts are typically found in reference(s) to radio and radar receivers. For example, meaningful FM tuner performance figures for sensitivity, quieting and signal-to-noise require that the RF energy applied to the antenna input be specified. These input levels are often stated in dBf (decibels referenced to 1 femtowatt). This is 0.2739 microvolt across a 75-ohm load or 0.5477 microvolt across a 300-ohm load; the specification takes into account the RF input impedance of the tuner.
