Prime Performance formula for measuring Throughput

Hi
This is related to PPM formula "Session Throughput" (Downlink and Uplink (Rx or Tx)) for ASR 5k devices, using bulkstats files.

In System there are next formulas:

- System Session Total Throughput Gbp
((8*(sessRxbytes+sessTxbytes))/900/1024/1024/1024)

- System Session Uplink Throughput Gbps
(8*(sessRxbytes))/900/1024/1024/1024

- SystemSessionDownlinkThrougputGbps
(8*(sessTxbytes))/900/1024/1024/1024

900 is the interval between bulkstats counters

Bulkstat reference is "Statistics and Counters Reference, StarOS, Rel18" (for ASR 5k devices)

This reference describes:
- sess-txbytes.- The number of downlink bytes...
- sess-rxbytes.- The number of uplink bytes...

The question is:
According to standards, which divisor is supposed to be used, 1024 or 1000?
(IEC standard, SI or Binary Prefixes)

Note:

900 is the interval between bulkstats counters, in seconds (15mn)
