I needed to convert X minutes to HH:MM (Hours:Minutes), I used the following code to accomplish this:

MINUTES = X; //some integer

var m = MINUTES % 60;

var h = (MINUTES-m)/60;

var HHMM = (h < 10 ? "0" : "") + h.toString() + ":" + (m < 10 ? "0" : "") + m.toString();

A very neat answer has been given by powtac in another question, where seconds were needed to be converted to the same format.

Changing his provided solution to fit your issue, the following prototype function can be used to convert minutes to HH:MM:SS string format.

String.prototype.minsToHHMMSS = function () {
    var mins_num = parseFloat(this, 10); // don't forget the second param
    var hours   = Math.floor(mins_num / 60);
    var minutes = Math.floor((mins_num - ((hours * 3600)) / 60));
    var seconds = Math.floor((mins_num * 60) - (hours * 3600) - (minutes * 60));

    // Appends 0 when unit is less than 10
    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}
    return hours+':'+minutes+':'+seconds;
}

// Use it as following:
myDecimalNumber.minsToHHMMSS();

See the working code in the snippet below:

String.prototype.minsToHHMMSS = function () {
    var mins_num = parseFloat(this, 10); // don't forget the second param
    var hours   = Math.floor(mins_num / 60);
    var minutes = Math.floor((mins_num - ((hours * 3600)) / 60));
    var seconds = Math.floor((mins_num * 60) - (hours * 3600) - (minutes * 60));

    // Appends 0 when unit is less than 10
    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}
    return hours+':'+minutes+':'+seconds;
}

var decimalMinuteString = '1.1783471074380165';

var timeString = decimalMinuteString.minsToHHMMSS();

var input = document.getElementById('input');
var output = document.getElementById('output');
input.innerText = decimalMinuteString;
output.innerText = timeString;

  Input: <span id="input"></span>

  Output: <span id="output"></span>

If this solution helped you, please upvote firstly powtac's answer as it is the base of the answer.

One line is:

new Date(minutes * 60 * 1000).toISOString().substr(11, 8);

Just use this one line:

new Date(minutes * 60 * 1000).toISOString().substring(11, 19)

For example:

148 minutes = 02:28:00
