In cgs units, one erg is 1 g cm2 s−2, equal to 1.0×10−7 J.
The imperial/U.S. units for both energy and work include the foot-pound force (1.3558 J), the British thermal unit (Btu) which has various values in the region of 1055 J, and the horsepower-hour (2.6845 MJ).
The energy unit used for everyday electricity, particularly for utility bills, is the kilowatt-hour (kWh), and one kWh is equivalent to 3.6×106 J (3600 kJ or 3.6 MJ). Electricity usage is often given in units of kilowatt-hours per year (kWh/yr). This is actually a measurement of average power consumption, i.e., the average rate at which energy is transferred.
The calorie equals the amount of thermal energy necessary to raise the temperature of one gram of water by 1 Celsius degree, at a pressure of 1 atm. For thermochemistry a calorie of 4.184 J is used, but other calories have also been defined, such as the International Steam Table calorie of 4.1868 J. Food energy is measured in large calories or kilocalories, often simply written capitalized as "Calories" (= 103 calories).
In physics and chemistry, it is still common to measure energy on the atomic scale in the non-SI, but convenient, units electronvolts (eV). The Hartree (the atomic unit of energy) is commonly used in calculations. Historically Rydberg units have been used.
In spectroscopy and related fields it is common to measure energy levels in units of reciprocal centimetres. These units (cm−1) are strictly speaking not energy units but units proportional to energies, with hc being the proportionality constant.
Statcoulumb is the unit of charge in cgs system.
A mole is a number, this is not different in cgsor SI or in whatsoever 'unit system'.So the answer is yes, it can be used in cgs-unit system(The same is true for analogons like 'dozen = 12' and 'gross = 144' and even for pi = 3.14......... etc.).
Calorie is the unit of heat energy in cgs system. One calorie is the heat energy required to raise the temperature of one gram of water through one degree Celsius. But in MKSA system of units, joule is used as the unit of heat energy. One calorie is equal to 4.180 joule. Calorie is usually used in bio chemical changes.

CGS is NOT common nowadays. MKS is common because the SI, the international system of units, is based on it.
The unit of energy in the CGS system is the erg. It is a small unit of energy equal to 10^-7 joules.
The cgs power unit is the erg, a dyne-centimeter.
In the CGS system, the unit of frequency is measured in hertz (Hz), just like in the International System of Units (SI).
The unit of energy in the centimeter-gram-second (CGS) system is the erg.
The cgs unit of current in electromagnetic system equivalent to 10 amperes is 10 amperes.
The unit of thermal conductivity in the cgs system is cal/(cmsK), where cal is the calorie, cm is centimeter, s is second, and K is Kelvin.
Statcoulumb is the unit of charge in cgs system.
CGS unit of time is Second,s.
The centimetre-gram-second system (abbreviated CGS or cgs) is a metric system of physical units based on centimetre as the unit of length, gram as a unit of mass, and second as a unit of time. All CGS mechanical units are unambiguously derived from these three base units, but there are several different ways of extending the CGS system to cover electromagnetism.CGS approach to electromagnetic units The conversion factors relating electromagnetic units in the CGS and SI systems are much more involved - so much so that formulas for physical laws of electromagnetism are adjusted depending on what system of units one uses. refer to link below for methods

The unit of work in the CGS (Centimeter-Gram-Second) system is erg. 1 erg is equivalent to 1 dyne force applied over a distance of 1 centimeter.
The SI unit for density is kg/m3In the CGS system, it is g/cci have no idea:P
