+## Memory Value Humanization
+
+VPA can present memory recommendations in human-readable binary units (KiB, MiB, GiB, TiB) instead of raw bytes, making resource recommendations easier to understand. This feature is controlled by the `--humanize-memory` flag in the recommender component.
+
+When enabled, memory values in recommendations will be:
+- Converted to the most appropriate binary unit (KiB, MiB, GiB, or TiB)
+- Displayed with up to 2 decimal places for precision
+- Applied to target, lower bound, and upper bound recommendations
+
+For example, instead of seeing a memory recommendation of `262144000` bytes, you would see `250.00Mi`.
+
+To enable this feature, set the `--humanize-memory` flag to true when running the VPA recommender:
+```bash
+--humanize-memory=true
