more info...

For this use case the format duration was chosen since the numeric value is being calculated, a number of milliseconds represents a time duration.

This way the value is represented like 2d 9h 43m instead of a single number.

Check the parameter Use time tracking settings

more info...

By checking this parameter, the duration will be based on the number of working hours per day, and the number of working days per week as configured in time tracking, instead of 24 hours per day and 7 days per week.

Add the field to the relevant view screens.

Remember: All calculated fields are read-only and cannot be manually updated on a create or edit screen.
