what is the difference between kilo.ohms and meg.ohms,
i,m starting to use multi meter in dignosis so it will clarify .
TIA

Note that if you abbreviate mega to M it must be a capital letter. 'm' stands for milli which is a thousandth of an Ohm. 'Ohm' should be written with a capital as the unit is named after a person. (look up SI units in Wikipedia for more information).

So are the volt, amp, and watt, among others. It's accepted convention that they may be written without an initial capital though.
Except when it's a kilo- or Mega- byte/bit, in which case it's 1,024 and 1,048,576
with MegaBit it's 1,000,000 bits..
with MegaByte it's 1,048,576 bits as it's binary and there are 8 Bits to a Byte..
with MegaByte it's 1,048,576 bits as it's binary and there are 8 Bits to a Byte..
How can you have got to this stage in your life and not know what a kilometer is, or a millimeter, or a kilogram...?
Depends on whether you're talking about memory or disk...
just clarifying .
Getting OT now, but technically a kilobyte / megabyte are just 1000 / 1000000 bytes - a kibibyte is 1024, and a mebibyte 1048576 (abbreviated to KiB and MiB). Unfortunately, manufacturers don't normally use these terms, and simply call things KB or MB and use whichever of 1000 / 1024 gives them a bigger number at the end...
Err — you're only out be a factor of 8 or so...
As BAS helpfully points out, it changes according to disk or memory. Anyway:
There are 8,000,000 bits in a Megabyte of hard disk space, 8,192,000 bits in a Megabyte of 3.5" floppy disk space and 8,388,608 bits in a Megabyte of memory. The conversions are what manufacturers of disk drives and semiconductors use.
As for the mebibyte, it'll never catch on. Well, not until JEDEC agrees with the maybes and giblets.
Is that formatted or unformatted?
Uuuurrgghhhh!! OK I can understand using either the SI prefix powers of ten definitions or the base 2 values, so both an 8,000,000bit or 8,388,608bit megabyte seem reasonable to me (mildly annoying though it is that the 320Gb hard drive I just installed in my PS3 only actually holds 298). But mixing the two!!
In what depraved computer scientist's sick mind was an 8,192,000bit megabyte a useful, or even meaningful figure?? 
memory is organised in 8-bit bytes, and you cannot have fractions of a byte so the number of bits in a kilobyte, megabyte, gigabyte, terrabyte etc HAS to be divisible by 8, and we still want kilobytes x kilobytes = megabytes, etc.
