Angularjs Convert Size (Bytes) to KB, MB, GB, TB in jQuery or JavaScript

May 5, 2015
Introduction

Here I will explain how to convert size bytes to kb, mb, gb or tb in
AngularJS or JavaScript or jQuery. By "Math" formulas we can convert size bytes to kb, mb, gb or tb in AngularJS or jQuery or JavaScript.


To get convet size (bytes) to kb, mb, gb or tb using AngularJS we need to write the code like as shown below


$scope.fnconvertsize = function () {
var bytessize = $scope.sizeinbytes;
var sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB'];
if (bytessize == 0)
$scope.convertedsize= '0 Byte';
var i = parseInt(Math.floor(Math.log(bytessize) / Math.log(1024)));
$scope.convertedsize = Math.round(bytessize / Math.pow(1024, i), 2) + ' ' + sizes[i];
}

If you want to check it in complete example you need to write the code like as shown below


<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Convert size (Bytes) to KB, MB, GB, TB in Angularjs</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.9/angular.min.js"></script>
<script type="text/javascript">
var myApp = angular.module('sampleapp', [])
myApp.controller("expressionController", function ($scope) {
$scope.fnconvertsize = function () {
var bytessize = $scope.sizeinbytes;
var sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB'];
if (bytessize == 0)
$scope.convertedsize= '0 Byte';
var i = parseInt(Math.floor(Math.log(bytessize) / Math.log(1024)));
$scope.convertedsize = Math.round(bytessize / Math.pow(1024, i), 2) + ' ' + sizes[i];
}
});
</script>
</head>
<body>
<form id="form1">
<div data-ng-app="sampleapp" data-ng-controller="expressionController">
<input type="number" ng-model="sizeinbytes"> <br/><br/>
<input type="button" ng-click="fnconvertsize()" value="Convert Size" /><br/><br/>
