Quick tool to convert time into decimal

I needed a quick tool that can convert say 20 minutes into decimal, as im doing this a lot these days. Here is what i come up with, well you can google it as well and that works, but this form is a bit easier. 

Just create a quick tool that takes time, e.g: 30 minutes and converts it into 0.5

And do a demo of the code required. Here are a few options that i found. 

Basic Conversion Calculations

Minutes = (Hours x 60) + (Minutes) + (Seconds / 60)
Minutes = (11 x 60) + (11) + (11 / 60)
Minutes = (660) + (11) + (0.18333333)
Minutes = 671.18333333.

Complex Conversion with hours mins and secons

<?php
$hms = "2:12:0";
$decimalHours = decimalHours($hms);
function decimalHours($time)
{
$hms = explode(":", $time);
return ($hms[0] + ($hms[1]/60) + ($hms[2]/3600));
}
echo $decimalHours;
?>

Nice simple one with hours and minutes

function convert($hours, $minutes) {
return $hours + round($minutes / 60, 2);
}

I went with this one, as its nice and basic for the demo.

  $hours = "";
}

function convert($hours, $minutes) {
  return $hours + round($minutes / 60, 2);
}

if(!is_numeric($minutes) || !is_numeric($hours) ) {
	$template_result .= "<p class='message'>Missing a valid time value </p>";
	return;
}

$decimal_time_val = convert($hours, $minutes);


$template_result .= "

  <div class='card-body'>
    <h5 class='card-title'>$hours Hours and $minutes Minutes as Decimal is</h5>
