Actual numbers to the human readable values

Question

I have data in bytes. I need to draw this values as human readable labels on a chart (like 2.5KB, 14MB etc.) and need to help with function (input data - actual value, output -

Answer 1

I love this implementation: clear and compact:

function readablizeBytes(bytes) {
    var s = ['bytes', 'kB', 'MB', 'GB', 'TB', 'PB'];
    var e = Math.floor(Math.log(bytes) / Math.log(1024));
    return (bytes / Math.pow(1024, e)).toFixed(2) + " " + s[e];
}

Usage:

readablizeBytes(10000000)
"9.54 MB"

I don't take the credit of this.
