  • Vishwas,

    you had the duration of the task set to 1 day.

    Then you went to file, options, schedule and changed the definition (or conversion factor) of "1 Day" to 7 hours.

    Any help?

    1. your original duration was 1 day.  Out of the box, 1 day = 8 hours (as defined in File | options | schedule | hours per day.  

    2. 8 hours is actually 480 minutes.  

    3. You then change the hours per day figure to 7 hours.  So, it now takes 8/7 of a day to do the work, = 1.14 hours.  

    If you were not using quite those times, you might see 1.13....

    1. Go to file, options, and choose a date/time format that displays the time as well as the date.
    2. Check what the working hours are in the project calendar.
    3. Count the working hours between the start and finish of a task with 1 day duration.
    4. Count the working hours between the start and finish of a task with 8 hours duration (input this as "8h").
    5. Check file, options, schedule for the hours/day setting.

    Try it. Get back to us with those numbers.
