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.

PHP

``````\$template_result = "";

\$get_form = "

";

\$template_result .= \$get_form;

if(isset(\$_POST['minutes'])) {
\$minutes = \$_POST['minutes'];
} else {
\$minutes = "";
}

if(isset(\$_POST['hours'])) {
\$hours = \$_POST['hours'];
} else {
\$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 .= "

Enter the number of hours to convert to decimal, default is 0.
