How to convert days to hours

Days and hours organize our calendar and daily schedules. One day equals exactly 24 hours, based on Earth's rotation period. Hours provide finer granularity for planning within a day.

Multiply days by 24 to get hours. Formula: hours = days × 24. 1 day = 24 h. 3 days = 72 h. 7 days (1 week) = 168 h. A 48-hour weekend = 2 days.

Project deadlines, medication schedules (every 8 hours = 3 doses per day), and travel itineraries use this conversion. Business hours: 5 days × 8 h = 40 h per work week.

Values: 0.5 day = 12 h, 1 day = 24 h, 2 days = 48 h, 30 days ≈ 720 h.
