# php – How to calculate hour:minutes from total minutes?

Questions:

For example i have 525 minutes, if we will divide it by 60 the result will be 8.75

But 1 hour have only 60 minutes not 75

How can i calculate the exact hour:minutes from total minutes?

``````\$hours = intval(\$totalMinutes/60);
\$minutes = \$totalMinutes - (\$hours * 60);
``````

Edited to be PHP

This kind of conversion is done using integer division and the modulo operator. With integer division you find out how many of the “large” unit you have and with modulo you find out how many of the “small” unit are left over:

``````define('MINUTES_PER_HOUR', 60);

\$total_minutes = 525;
\$hours = intval(\$total_minutes / MINUTES_PER_HOUR);  // integer division
\$mins = \$total_minutes % MINUTES_PER_HOUR;           // modulo

printf("%d minutes is really %02d:%02d.\n", \$total_minutes, \$hours, \$mins);
``````

`floor(525 / 60)` gives the number of hours (`8.75` rounded down to `8`).
`525 % 60` gives the number of minutes (modulo operator).
