How 7 days converts to hours

1 day = 24 hours 7 × 24 = 168
Where 7 days shows up
A week is the largest unit that stays perfectly regular, which is why 168 turns up wherever capacity gets planned: shift rotas, server uptime, personal time budgets. The arithmetic that makes it useful is blunt. Eight hours of sleep a night claims 56 of the 168, exactly a third, and a 40-hour job takes another 23.8 percent. What is left over, 72 hours, is usually the number people are actually after when they look this up.
