A wattmeter measures power, which is the rate of doing work, expressed in watts.An energy meter measures the amount of energy consumed, usually in kilowatt hours.The meter on the wall of your house is an energy meter.
The kilowatt hour (KWHr) measures electricity use.
A wattmeter measures the amount of electrical power in watts being consumed by a device or circuit. It typically consists of a current and voltage measurement component to calculate the power in watts.
Oh my god
A power surge is unlikely to cause a significant increase in the kWh reading of a digital meter because the meter measures the amount of electricity consumed over time, not the voltage of the electrical supply. Power surges can cause damage to electronic devices but typically won't directly impact the kWh reading on a meter.

A PHCN meter measures electric power for prepaid meters in Nigeria.
A VAr meter only measures the reactive (imaginary) power. Apparent power is a combination of real and reactive power; thus having a VAr meter will not suffice to measure apparent power. Likewise, because the VAr meter only measures reactive power, it does not provide any information on real power.
An energy meter measures power and time; a wattmeter measures an instantaneous value of power. Energy = Watt/seconds.
The Ammeter XD
The kilowatt hour (KWHr) measures electricity use.
In order to have the need for a laser power meter, people first need to have a strong laser. The meter measures the strength of the laser in order to understand what kind of damage it could cause.
The most common acoustic measurement tools are the Loudness Meter, and the Real-Time Analyser. The Loudness meter measures dbSPL. The Real-Time Analyser measures the power of individual frequency bands.
A kilogram cannot be compared to a meter. The kilogram measures mass and the meter measures length.
First, shut off all power to your house.
A bike power meter measures the power output of a cyclist by using strain gauges to detect the force applied to the pedals. This data is then combined with the speed of the cyclist to calculate power output in watts.
No can do, one measures length, one measures area...
