A watt meter will measure active power, not reactive power.
The Watt is the unit used to measure electric power :)
A dynamometer measures force, torque, and power. It can be used to measure the power of an engine.
Watts are commonly used to measure power generated by an object.
The standard unit used to measure sound power is the decibel (dB).

A dynamometer is used to measure force, torque or power of a engine. A dynamometer also can measure the torque and power needed to power a given driven machine.
The different optical power units used to measure the intensity of light in optical systems are diopters and watts. Diopters measure the refractive power of a lens, while watts measure the total power of light emitted or transmitted through a system.
The ratio between two quantities, usually quantities that somehow measure power, or intensity (power / area).
No, you can't.
