The current quota documentation doesn't show all unit suffixes that are allowed. For example, milli (m) for CPU, etc.
Related issue: https://github.com/openshift/openshift-docs/issues/439 (regarding, specifically, the definition of "cpu unit").
See also https://access.redhat.com/articles/1531823 which includes a nice table describing the valid suffixes for the "resource-quantity" type used for resource limit values.
