Convert days to milliseconds

Explanation

From this page you can convert days to milliseconds (or d to ms) simply, by using the application above.

In case you are wondering, to convert from days to milliseconds you need to multiply by 86400000. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 d=86400000 ms

The day (d) is a common unit of measurement of time. It is accepted for use with the SI.

One day can be divided into 24 hours of 3600 seconds each and 365 days make a year.

Definition of the day

One day is equal to 86400 seconds.

Some Facts

The longest period of sleep deprivation scientifically documented is 11 days. That is not something you want to try though, like other animals, humans need regular sleep for their brain to function correctly. The symptoms of a lack of sleep can be light at first. They include moodiness, irritability and a shorter attention span. But after days of sleep deprivation the patient can suffer from hallucinations, paranoia and even die. So turn off netflix, it's not worth it.

A sexagesimal system

Hours, minutes and seconds are an example of a sexagesimal or base 60 numeral system.

The number 60 is a superior highly composite number, meaning it has a lot of factors. This allows for some simplification when dividing.

Since there are 60 minutes in an hour, the hour can be divided evenly in eleven different ways (with sections of 30, 20, 15, 12, 10, 6, 5, 4, 3, 2 and of course 1 minute).

Coming up with and remembering 60 different symbols would be cumbersome, that is why we write the sexagesimal digit using the decimal system.

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.
