Kbit vs kbit

Been asked to provide Constant Bitrate files at 3000 Kbit/s or better for a non broadcast playback system. I am currently confusing myself about Kbit vs kbit Vs Mbit. Can someone point me in the right direction...

8 bits to a Byte is the basic math.

Craig,

I get the basic math its the K vs k that has me questioning myself. If I am setting this up in Compressor I can set kbits/s so I am assuming if they want 3000 Kbits/s I can set up 30000 kbits/s... yes?

Craig,

Just want to make sure I am on the right path. Kbit is a decimal expression (1000 bytes) and kbit is binary (1024 bytes) so if they are looking for 3000 Kbits/s I can go 3072 kbit/s... ?

And can anyone weigh in on the non overt nature of Compressor regarding doing CBR h.264 files. Do I set up as Download to not get VBR?

I see where the issue is now.
binary vs decimal.
The program I linked to uses
KiB for binary and KB for decimal

I believe the assumption is binary for data rates. That's not the case with "sizes."

but look at this too.

kbits and Kbits are the same.
Kb and KB can be different though. b is bit and B is Byte
