calculate minutes into hours

Space_Cowboy

Hi there,

Im creating a job sheet system, where people enter how many minutes they have spent on a job.
The minutes are totaled up and im left with a total like: 465 (minutes).
I need something that will break that down into hours. (465 minutes is equal to 7 hours and 45 mins).
If I try this calculation: 465 / 60 it equals 7.75. It needs to be 7.45 and I cant find the answer anywhere 

Any help would be massively appreciated

7.75 hours is 7 hours and 0.75 hours. Since 0.75 hours is 0.75 * 60 = 45 minutes... you get 7 hours 45 minutes. So, if you are writing a program to do this, you might compute 465 mod 60 to give you 45 minutes, and compute with integer division 465 / 60 = 7 hours. (In the case of PHP, you can simply cast the result to int to get the truncation that results from integer division).

// function to convert minutes into hours and minutes for a jobsheet.
function timer($job)
{ 
$hours =  floor($job/60); // No. of mins/60 to get the hours and round down
$mins =   $job % 60; // No. of mins/60 - remainder (modulus) is the minutes
echo "Job = " . $hours . " Hours " . $mins . " Minutes ";
}
// usage: wrap the function around your number of minutes:
timer(465);

If you want to do it that way, then it would be better as:

// function to convert minutes into hours and minutes for a jobsheet.
function convertFromMinutes($job_duration)
{
    $hours = (int)($job_duration / 60);
    $minutes = $job_duration - ($hours * 60);
    return array('hours' => $hours, 'minutes' => $minutes);
}

$job_duration = 465;
$job_duration = convertFromMinutes($job_duration);
echo "Job duration = " . $job_duration['hours'] . " Hours "
    . $job_duration['minutes'] . " Minutes ";
