Our efficiency calculator tool will help you quickly determine the effectiveness of your processes by comparing the input and output values.

Efficiency Calculator

Work Output (in joules): Work Input (in joules): CalculateEfficiency (%):

This calculator measures the efficiency of a system, which is calculated by dividing the work output by the work input and then multiplying this ratio by 100 to get the efficiency percentage.

How to Use the Calculator

1. Enter the work output of the system (in joules).
2. Enter the work input of the system (in joules).
3. Click on the “Calculate” button to see the efficiency percentage.

How Efficiency Is Calculated

The formula used for calculating efficiency is:

Efficiency (%) = (Work Output ÷ Work Input) × 100

Limitations

Note that this calculator assumes that both work output and work input are provided in the same units (joules). Also, it cannot account for measurement inaccuracies or losses not reflected in the work input.
