## How to convert days to hours (d to hr)

The formula for converting days to hours is: hr = d × 24. To calculate the day value in hours first substitute the day value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 day in hours we follow these steps:

hr = d × 24

hr = 1 × 24

hr = 24

In other words, 1 day is equal to 24 hours.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 8 days to hours is:

- Understand the conversion formula: hr = d × 24
- Substitute the required value. In this case we substitute 8 for d so the formula becomes: hr = 8 × 24
- Calculate the result using the provided values. In our example the result is: 8 × 24 = 192 hr

In summary, 8 days is equal to 192 hours.

## Converting hours to days

In order to convert the other way around i.e. hours to days, you would use the following formula: d = hr ÷ 24. To convert hours to days first substitute the hour value into the above formula, and then execute the calculation. If we wanted to calculate 1 hour in days we follow these steps:

d = hr ÷ 24

d = 1 ÷ 24

d = 0.0416666666666666666666666666667

Or in other words, 1 hour is equal to 0.0416666666666666666666666666667 days.
