Days to Hours
3 days is 72 hours, because a day is 24 hours and 3 times 24 is 72. Use the Hour format to turn any number of days into total hours.
Project planners and shift schedulers run this conversion when a task estimated in days has to slot into an hourly timesheet or a billing tool. A two-week sprint, for example, is easier to staff once you see it as 336 hours. The rule is simple: one day equals 24 hours, so multiply the day count by 24.
FormulaMultiply the number of days by 24 to get hours, so 5 days × 24 = 120 hours.

Common questions
How many hours is 7 days?
7 days is 168 hours. Multiply 7 by 24 to reach 168. That figure is the basis for a standard week, which is why weekly on-call rotations and 168-hour billing cycles line up exactly with seven full days.
What if I have a fraction of a day, like 1.5 days?
Multiply the fractional day by 24 the same way. 1.5 days × 24 = 36 hours, and 2.25 days × 24 = 54 hours. To go the other direction, divide your hours by 24 to recover the days.
