Unfortunately, our bean counters started using 60K for $60,000. When the mainframe 3380 came out they decided to start counting disk in 1000s and 1000000s. This has just perpetuated on for disk to make it easy for people to calculate the space required because data records are measured in base 10 not base 2. So, we are stuck with it. TSM uses the open systems calculation, 1024.

(Not CASE is very important) 1 Byte = 8 bits 1 kB = 1024 Bytes 1 MB = 1024 kB = 1024 * 1024 Bytes 1 GB = 1024 * 1024 * 1024 Bytes m - milli c - centi d - deci (Not often used I admit) k - kilo M - Mega G - Giga b - bit B - Byte These are particularly important when you start swapping between serial speeds (Usually quoted in bits) and Size (Usually quoted in Bytes). e.g. EThernet is most commonly 100Mbps (100 Mega bits) while 100MB is 100 Mega Bytes. 8* larger...
