Clarification needed: 1 megabit = ? kilobits

Hello! When I go to Queues-> Queue Type → my PCQ queue(pcq-download), and want to select that the PCQ Burst Rate has the same value(1M in my example) as PCQ Rate(1M), I get this error: Couldn’t change Queue Type - pcq-burst-rate less than pcq-rate (6)". That’s ok. The PCQ Burst Rate needs to have a bigger value than PCQ Rate.
But, If I type 1024k instead of 1M in the Burst Rate field, I don’t get any error (See picture1 in the attachment.).

How does ROS calculate these values? Is 1 Mbit/s = 1000 kbit/s, or is 1 Mbit/s = 1024 kbit/s?

1000 actually :slight_smile:

In datacommunication it is always the same as in the real world :wink:
1K = 1000
1M = 1000000 = 1000K
1G = 1000000000 = 1000M = …

Ok. Thank you!

Only in the data storage is where 1M = 1024K :slight_smile:

Well.. Not everyone agrees with that :slight_smile:
Drive manufacturers also use ‘1K’ for ‘1000’. Linux (and probably other OSs also) show size in 1000 = 1K or 1024 = 1Ki. See http://en.wikipedia.org/wiki/Binary_prefix for more information.
