## How to convert days to milliseconds (d to ms)

The formula for converting days to milliseconds is: ms = d × (24 × 60 × 60 × 1000). To calculate the day value in milliseconds first substitute the day value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 day in milliseconds we follow these steps:

ms = d × (24 × 60 × 60 × 1000)

ms = 1 × (24 × 60 × 60 × 1000)

ms = 86400000

In other words, 1 day is equal to 86400000 milliseconds.

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 3 days to milliseconds is:

- Understand the conversion formula: ms = d × (24 × 60 × 60 × 1000)
- Substitute the required value. In this case we substitute 3 for d so the formula becomes: ms = 3 × (24 × 60 × 60 × 1000)
- Calculate the result using the provided values. In our example the result is: 3 × (24 × 60 × 60 × 1000) = 259200000 ms

In summary, 3 days is equal to 259200000 milliseconds.

## Converting milliseconds to days

In order to convert the other way around i.e. milliseconds to days, you would use the following formula: d = ms ÷ 8.64e+10. To convert milliseconds to days first substitute the millisecond value into the above formula, and then execute the calculation. If we wanted to calculate 1 millisecond in days we follow these steps:

d = ms ÷ 8.64e+10

d = 1 ÷ 8.64e+10

d = 0.0000000000115740740740740740740740740741

Or in other words, 1 millisecond is equal to 0.0000000000115740740740740740740740740741 days.
