Well, I used 5500 as total packet size,
Is this correct?

No not yet, but I figured out a formula for bandwidth and bandwidth
percentage

byte-count/Total-byte-count * Bandwidth * .75

example: Bandwidth 128k

www byte count 1500 in custom queue list

1500/4500= .333 * 128 = 42.624 * .75 =31.968 (32k of bandwidth)

Bandwidth percentage

byte-count/Total-byte-count * .75

1500/4500= 33 * .75 = 24.75% (25% of bandwidth)

Let me know if this makes sense or if you feel this is the correct approach.

Did someone answer this for you yet?
If not, here is what I have..
I am trying to do this with our router. It should be close. Please compare
with answers you got and let me know if this is correct. I am also trying to
learn this....

Class map www
Match match-all protocol www
Class map dns
Match match-all protocol dns

Policy map ccie1
Class www
Bandwidth 52
Que-limit 100
Class dns
Bandwidth 17
Que-limit 100
Class class-default
Bandwidth 26

Interface ser 0/0
Service policy ccie1 out

Assuming ar = 128

Given the Custom Queue below, could someone show me an example on how to
convert this to a CBWFQ list.

queue-list 1 protocol ip 1 tcp www
queue-list 1 protocol ip 2 tcp dns
queue-list 1 default 3
queue-list 1 queue 1 limit 100
queue-list 1 queue 1 byte-count 3000
queue-list 1 queue 2 limit 100
queue-list 1 queue 2 byte-count 1000
queue-list 1 queue 3 byte-count 1500
