To convert 1 day, 9 hours, and 35 minutes into a single unit of time, start by converting each component to the smallest unit. 1 day is equal to 24 hours, so 1 day is equivalent to 24 hours. Next, add the 9 hours to the initial 24 hours, resulting in a total of 33 hours. Lastly, include the 35 minutes, which is equivalent to 0.58 hours (35 minutes ÷ 60 minutes).

Therefore, adding 33 hours and 0.58 hours gives a total of 33.58 hours. This calculation simplifies the original time duration of 1 day, 9 hours, and 35 minutes into a single unit of 33.58 hours. This consolidated value is useful for comparing time durations and scheduling events accurately.
