Determining File Size
:( To calculate the size of a file, say, Tester.xls, we use: Format(FileLen("Tester.xls")*0.0009767,"0") & "KB" Can someone explain the use of the the factor* 0.0009767* (rather than the customary .001) in converting the bytes into Kilo Bytes?

Determining File Size
Thanks Leith and Bob for the explanation. By the way, isn't it strang that a "kilo" for once doesn't denote 1,000?

Determining File Size
I think the program considers 2^10, or 1,024 to be a kilobyte. instead of
1,000. Therefore, the ratio 1 kb / 1024 , equals 0.0009765625.

Determining File Size
Diana, So by logical extension, can I construct *I mega-byte* as: I mg = 1 million bytes (approx) = 1 Kb (Excel's) x 1,000 approx. = (2 ^10 )bytes x 1,000 approx =(2 ^10 )bytes x 2 ^10 = 2^20 bytes = 1,048,576 bytes ? Hence, to convert N bytes to Megabytes, the correspondin multiplication factor could be 1/1048576 = 9.5367 x 10^ -- david ----------------------------------------------------------------------- davidm's Profile: http://www.excelforum.com/member.php...fo&userid=2064 View this thread: http://www.excelforum.com/showthread.php?threadid=47704 |
