Based on the provided knowledge sources, it appears that ratio metrics defined via fact tables in GrowthBook are not automatically displayed as percentages. However, there is an ongoing discussion and feature request to address this issue. According to a forum conversation, a user reported that their ratio metric was rendering as 0.578 instead of 57.8% [Forum Conversation](https://linen.growthbook.io/t/16339705/hey-is-it-possible-to-determine-the-format-a-metric-is-displ). In response, a GrowthBook representative acknowledged this and opened an issue to allow forcing the rendering of ratio metrics as percentages [GitHub Issue](https://github.com/growthbook/growthbook/issues/2249). The GrowthBook representative stated: > "IMO this is not a bug, but we should allow you to force it to render as a percentage (at least when the numerator and denominator are in the same column type)." Currently, GrowthBook has custom logic to try and determine the correct format for ratio metrics, but it doesn't always result in percentage display [Forum Conversation](https://linen.growthbook.io/t/16339705/hey-is-it-possible-to-determine-the-format-a-metric-is-displ). It's worth noting that this limitation applies specifically to ratio metrics created using fact tables. The ability to display these metrics as percentages is a requested feature but not currently available out-of-the-box.
