Memory unit representation in Kubernetes API

I am querying the API to get Node information and in the JSON result I see the information about CPU as below

What does this “Ki” at the end of the memory mean? Is it KiloBytes?

Ki is “kibi”: - 2^10 (as opposed to “kilo”: 10^3).

Thanks for the clarification.

The “quantity” type for that field can take either bare numbers (1024)
or SI suffixes (1.024K) or binary suffixes (1Ki), and they all mean
the same
