If you mean kbs as killabites then there is 1000 kb in a mb therefore there is 400 kb in 0.4 of a mb
1,024 kilobytes (KB)
51200 KB in 50 MB
1 megabyte is equal to 1024 kilobytes.
1 MB = 1024 KB hence 30720 KB = 30720/1024 = 30 MB
One Mb is equal to 1000 kbs.... so 117 Megabytes (Mbs) or .117 Gigabytes(Gbs)
MBs(MegaBytes) Are larger than KBs(KiloBytes)
Well their are 1000 kilobytes in 1 Megabyte so it would approximately be 8.7 Megabytes/second.
It depends on how you encode the music. I encode my songs to 64 kbs WMA but some people with a good ear for music find that too low quality and 128 kbs is considered the minimum encoding. 256 might be needed if you have a very good ear for music. At 128 kbs you will fit 300-400 songs on a 1GB player. At 64 kbs twice that number and 256 kbs only 150 or so.
MB is more, 1 MB = 1024 KBs Heres the list from Least to greatest, Bytes, Kilo-Bytes, Mega-Bytes, Giga-Bytes, Terra-Bytes
.624 MB it takes 1024KB to make 1MB
5 kilobytes = 0.0048828125 megabytes
