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.

The petawatt (PW) is equal to one quadrillion (10¹⁵) watts and can be produced by the current generation of lasers for time-scales on the order of picoseconds (10⁻¹² s). One such laser is the Lawrence Livermore's Nova laser, which achieved a power output of 1.25 PW (1.25×10¹⁵ W) by a process called chirped pulse amplification. The duration of the pulse was roughly 0.5 ps (5×10⁻¹³ s), giving a total energy of 600 J.
