Compare two volumes

Enter two values expressed in the same unit. The tool shows the absolute gap, which value is larger, their ratio and a visual comparison.

Example

For example, values 10 and 15 differ by 5 units; the second is 1.5 times the first.

How to read the result

The gap is the absolute difference between A and B. The ratio answers “how many times?”, while the percentage difference compares the gap with the average magnitude of the two values.

A percentage difference is useful for relative comparison, but it does not replace the absolute gap. Always keep the unit and the real-world scale in view.

Percentage difference is symmetric: swapping A and B does not change the result. Percentage change is directional and does change when the reference value changes.
