Goldilocks dashboard shows memory recommendation in megabytes units (M), which is 10^6 of bytes.
Mebibytes (Mi) instead use as base powers of 2.

Usually Kubernetes memory requests are specified in Mi and also different tools, like default Prometheus Operator Grafana dashboard show in MiB units.

As a feature option to switch between different types of measurements can be added.

From Kubernetes docs:

Limits and requests for memory are measured in bytes. You can express memory as a plain integer or as a fixed-point integer using one of these suffixes: E, P, T, G, M, K. You can also use the power-of-two equivalents: Ei, Pi, Ti, Gi, Mi, Ki. For example, the following represent roughly the same value:

128974848, 129e6, 129M, 123Mi
