JavaScript Data Capacity Unit conversion (KB,MB,GB,TB)

For example, when we refer to "data transfer speed" and "hard disk storage space", kilobytes represent 1000 (103), and when it comes to memory or CPU cache capacity, kilobytes represent 1024 (210) because they are stored here by byte-code address.



In practical applications, we often need to convert bytecode to KB, MB, GB, and so on, where we use JavaScript to convert bytecode:


The code is as follows

function Bytestosize (bytes) {
if (bytes = = 0) return ' 0 B ';
var k = 1000,//or 1024
sizes = [' B ', ' KB ', ' MB ', ' GB ', ' TB ', ' PB ', ' EB ', ' ZB ', ' YB '],
i = Math.floor (Math.log (bytes)/Math.log (k));

Return (Bytes/math.pow (k, i)). Toprecision (3) + ' + sizes[i];
}
