ECS: The capacity unit of the ECS differ between the UI and REST API (GiB vs GB)

Summary: The capacity of, for example, 10 GB displayed by svc_bucket is apparently taken directly into the UI metering output (or the opposite way), that is with the same value is displayed only with GiB. ...

Note the GB unit in CLI and REST API Commands:

But checking the UI metering information we do see the same reading in GiB instead of GB, what seems not to be correct:

UI metering information

 

If we hover over the 11.00 GiB, it shows in bytes.
hovering over the 11.00 GiB in the UI shows in bytes. 

 

11 GB = 11 * 1000^3 = 11000000000 bytes
11 GiB = 11 * 1024^3 = 11811160064 bytes

 

Cause

The values returned in the UI and the command line are both GiB. At the command line, the unit is displayed as GB instead of GiB which is wrong. 
So the GiB values in the metering page are correct.

Resolution

The capacity reading of CLI or REST API commands are true and are matching the UI metering reading. A future ECS code version fixes the CLI/REST API capacity units from GB in GiB.
