Yes, it can be measured. Coulombs is a measure of charge. 1 ampere second = 1 coulomb. With DC current you simply multiply your current by time applied. For alternating current you would need to integrate, Although if all you have are data points, (which is more likely) you would probably use Simpson's Rule to approximate the amount of charge. Keep in mind that Coulombs is a scalar quantity (an amount) and Ampere's is a vector quantity. so Ampere has a magnitude and direction.
The other way you can measure Coulombs is to count electrons. take the number of electrons and divide by 6.24e18 (the approximate number of electrons to make a coulomb). But I'm unsure on how to count individual electrons.

There is no such thing as 'electrical power' or 'mechanical power' or, in fact, any other sort of power. Power is simply a rate -the rate of doing work. In SI, power is measured in watts. An obsolete unit of power is a horsepower. Although, in the Unites States, the power of an engine is usually measured in horsepower, elsewhere it is measured in watts (or, more usually, kilowatts).So, when an engineer describes converting electrical power to mechanical power, what he actually means is the rate of converting electrical energy to mechanical energy.
Resistance is an opposition to electrical currrent flow, which is more formally coulombs per second, or amperes. Voltage is electrical pressure, more formally joules per coulomb. When you multiply volts and amperes you get joules per second, or watts.
Generally speaking, the electrical energy consumption of low-power electronics circuits is measured in watt.hours (W.h) whereas the energy consumption of household appliances and most other pieces of equipment, apparatus or machinery that take more power than items which only have low-power electronics circuits in them is measured in kilowatt.hours. (kW.h)
Amperes are a unit of electrical current flow, in coulombs per second. Volts are a unit of electrical potential difference, in joules per coulomb. The two units can not be converted without some intervening device characteristic such as resistance or power.
an electrical charge is measured in Coulombs, which is equal one ampere-second. That is, one ampere of current through a plane is equivalent to one coulomb of charge passing through the plane per second.Current
Coulombs. 1 Coulomb = 6,241,510,000,000,000,000 electron or proton charges (rounded to the nearest 10 trillion)
Charges, whether moving or not, are measured in coulomb, not in amperes.Amperes is the unit of current - coulombs per second.
Electrical power is commonly measured in watts (W), which represents the rate at which energy is used or produced.
Watts.
Electrical power is expressed in watts or in jouls per secondAnother AnswerThere is no such thing as 'electrical power'. Power is simply a rate: the rate of doing work. Power can be measured in watts (in the SI system) or in horsepower (in the Imperial system). There is no reason why the power of a heater can't be measured in horsepower or the power of a car can't be measured in watts.
Resistance is measured in ohms.By Ohm's law, resistance is voltage divided by current, which is (joules per coulomb) divided by (coulombs per second), which is joules-seconds divided by coulombs squared. (It is easier to just say ohms.)
The units of charge are coulombs (C). Charge is measured using a device called an ammeter, which measures the flow of electric current in coulombs per second.
Lots of units are used to measure electricity, depending on what aspect you want to measure. For example: Voltage is measured in volts Current is measured in amperes Resistance (as well as impedance) is measured in ohms Power is measured in watts Capacitance is measured in coulomb Inductance is measured in henries etc.
Electrical current is measured in amperes (A), voltage is measured in volts (V), and resistance is measured in ohms (Ω). Power is measured in watts (W), and energy is measured in kilowatt-hours (kWh).
Electrical current is the number of elementary charge units (coulombs) that pass by a given point in one second. Current, measured in amperes, is coulombs per second. Electrical voltage is the "pressure" behind that current. Voltage, measured in volts, is joules per coulomb.
