# Convert 15 day to ns

In this article I will show you how to convert 15 days into nanoseconds. Throughout the explanation below I might also call it 15 day to ns. They are the same thing!

## How to Convert Days to Nanoseconds

A day is greater than a nanosecond. I know that a day is greater than a ns because of something called conversion factors.

Put very simply, a conversion factor is a number that can be used to change one set of units to another, by multiplying or dividing it. So when we need to convert 15 days into nanoseconds, we use a conversion factor to get the answer.

The conversion factor for day to ns is:

1 day = 86400000000000 ns

Now that we know what the conversion factor is, we can easily calculate the conversion of 15 day to ns by multiplying `86400000000000` by the number of days we have, which is 15.

15 x 86400000000000 = 1.296E+15 ns

So, the answer to the question "what is 15 days in nanoseconds?" is 1.296E+15 ns.
