The JS code is as follows:

var size = ' 8164674 '; function bytestosize (bytes) {    ifreturn ' 0 B ';     var // or 1024x768        sizes = [' B ', ' KB ', ' MB ', ' GB ', ' TB ', ' PB ', ' EB ', ' ZB ', ' YB '],        = Math.floor (Math.log (bytes)/ Math.lo G (k));     return (Bytes/math.pow (k, i)). Toprecision (3) + "+ Sizes[i];} Console.log (Bytestosize (parseint (size)));


The next two storage units are described: Bits, bytes

Bit: "Bit" is the smallest unit of data in an electronic computer. The status of each bit can only be 0 or 1.

Word: "word" consists of a number of bytes, the number of bits is called word length, different grades of machines have different length of words. For example, a 8-bit machine, its 1 characters equals 1 bytes, and the word length is 8 bits.

KB: is 1024 bytes

MB: Is 1024 kb

GB: is 1024 MB

TB: is 1024 GB

Common conversion units 1, bit, and byte conversions

1 bit (bits or bit) equals 0.125B (byte byte)

1 B (byte byte) equals 8 bit (bit or bit)

2, megabytes and kilobytes

1KB (kilobyte kb) equals 0.0009765625 MB (MBytes)

1MB (MBytes) equals 1024KB (kilobyte KB)

3, megabytes and gigabytes

1MB (MBytes) equals L 0.0009765625 GB (Kbytes)

1GB (gigabyte) equals 1024MB (MBytes)
