Hour (abbreviations: hr, or h): is a unit of time, conventionally counted as 1/24 of a day. In the modern metric system, it is equivalent to 3,600 seconds.

Day (abbreviations: dy, or d): is a unit of time. In common usage, it is either an interval equal to 24 hours or daytime, the consecutive period of time during which the Sun is above the horizon. As well, it is equivalent to a solar day, the period of time during which the Earth completes one rotation with respect to the Sun.

How to Convert Hours to Days

Example: How many days are equivalent to 94.91 hours?


1 hours = 0.041666666666667 days

94.91 hours = Y days

Assuming Y is the answer, and by criss-cross principle;

Y equals 94.91 times 0.041666666666667 over 1

(i.e.) Y = 94.91 * 0.041666666666667 / 1 = 3.9545833333333 days

Answer is: 3.9545833333333 days are equivalent to 94.91 hours.
