Days to Hours
A day is 24 hours, based on one full rotation of the Earth on its axis. An hour is 60 minutes, the standard unit for work schedules, travel times, and daily planning. 1 day equals 24 h, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to time, measured here against time's base unit (s) — every other time unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
h = day × 24
day = h × ≈0.0416667
Worked example: 5 day × 24 = 120 h.
