Velocity
The number of kilowatts used by a device in one hour. This gives you the rate at which energy is consumed.

Efficiency
To accurately measure the brightness and efficiency of fluorescent bulbs, one can use a device called a light meter to measure the amount of light emitted by the bulb in lumens. The efficiency of the bulb can be calculated by dividing the number of lumens produced by the amount of power consumed in watts. This will give you a measure of how effectively the bulb is converting electricity into light.

There is no direct conversion between lumens and watts as they measure different things. Lumens measure the total amount of visible light emitted by a source, while watts measure the amount of energy consumed or produced. The equivalence between lumens and watts depends on the type of light source (i.e., incandescent, LED, etc.) and their efficiency.
Efficiency itself is impossible to measure directly. The classic practical definition is to measure all of the waste produced by the operation (heat, material, labour hours, etc.) and divide them all by the amount of acceptable product produced. You will never get to 'zero', but if the fraction is reduced, efficiency has increased. Good luck, Quality Assurance is the most difficult part of manufacure, but it can be the most rewarding.
Efficiency is output power divided by input power. You somehow have to measure, calculate, or estimate both; the details will vary depending on the type of energy input and energy output.
to what extent does profitability of a firm measure its efficiency
The free energy (delta G) is the measure of the amount of energy produced or consumed in a reaction. Enthalpy (delta H) is a measure of the amount of heat produced or consumed in a reaction. These two quantities can sometimes be the same. When they are not, the other missing component where heat can be consumed or produced is work.
Business companies often measure productivity by the output produced during a specified time period. Efficiency, on the hand, relates to the quality of work in creating output with less waste and using fewer resources.
To accurately measure energy, one can use instruments like a wattmeter or a calorimeter. These devices can measure the amount of energy consumed or produced in a system. Additionally, formulas such as the energy balance equation can be used to calculate energy based on known parameters.
