About this percentage to ratio tool
Some formats prefer ratios rather than percentages. This tool converts a list of percentages into a clean ratio using whole numbers. Enter the percentages separated by commas or spaces and the calculator scales them to integers and reduces them to the smallest whole-number form. The proportions are preserved, so 40, 35 and 25 will become 8:7:5. It is useful for recipes, component mixes, team splits and any time a ratio looks better than a list of percentages in your document.
Results are simplified automatically using the greatest common divisor. If your percentages include decimals, the tool handles them by scaling, then reducing, so the final ratio is neat and readable. If the original percentages do not sum to 100, that is fine. Ratios work on relative size, not the absolute total. Use this when you need a quick conversion before sharing a plan or sketching an option. Stable Numbers aims to keep small jobs like this simple so you can move fast without mistakes.
