Why the number is exact
A week is defined as exactly 7 days, and a day is defined as exactly 24 hours. Since both of those relationships are fixed by definition rather than measured, multiplying weeks by 168 always gives an exact, whole number of hours.
When you'll use it
Adding up total work hours across a multi-week timesheet, estimating project duration in hours, and converting vacation or leave periods quoted in weeks into the hours a payroll system tracks.
