Hello everyone!



I’ve got several cols (days of the week) that have a time that I wasted in doing a task in minutes (ex: 120). All that I’m trying to do is a SUM of this minutes but in a h:mm format.



Example: The task is “Book Design” and the minutes I’ve spent in doing that task are (120, 120, 60, 60, 30). The SUM of that minutes is 390… that’s 6:30 hours. All I want to have is this number 6 and I don’t know how to get it.



Thanks in advance!

Airtable doesn’t allow formatting of number fields as durations (which is strange), but it DOES allow the formatting of formula fields as durations.



So just create a formula field that equals the number of minutes that you’re looking to display, and then format the field as a duration.


Welcome to the Airtable community!



One hour is 60 minutes, so 360 minutes is 6 hours (360 / 60). I’m not sure how you are getting 6 hours and 30 minutes.



How to get the sum of 6 hours depends on the field types of the initial values of minutes. If they are number fields, you can sum the minute fields and divide by 60.


For example, SUM({Monday}, {Tuesday}, {Wednesday}, {Thursday}, {Friday}) / 60



On the other hand, if your minute fields are duration fields (which sounds unlikely), you should know that duration fields are stored internally as a number of seconds, so you will need to convert seconds to hours. 1 hour = 3600 seconds.



If you want to format a numeric result as a duration in the formula settings, also keep in mind that the formula should calculate a number of seconds (not minutes).

Thanks for the correction, @kuovonne! Yes, @Rafa_Ramos — I meant seconds, not minutes.


Finally I made a formula field like this: SUM({Monday}, {Tuesday}, {Wednesday}, {Thursday}, {Friday}) * 60 and I assigned the formatting (format: duration, duration format: h:mm).



Example: Monday=1440, Tuesday=30, and the other days are equal to 0. Result=(1440+30)60=147060=88200. This number (88200) will be shown as a duration field (h:mm). The result is 24:30
