The efficiency formula is a mathematical expression used to measure the efficiency of a process or system. It is calculated by dividing the output of a process or system by the input, and then multiplying the result by 100 to get a percentage. The higher the percentage, the more efficient the process or system is. This formula is often used in business and engineering to measure the effectiveness of production processes, manufacturing systems, and other operations. For example, if a manufacturing system produces 10 widgets with 10 units of input, the efficiency formula would be 100%, meaning the system is 100% efficient. The efficiency formula can also be used to compare different processes or systems, allowing businesses to identify which processes are the most efficient and make the best use of resources.
