How many seconds are in a 24 hour day?

Hours, minutes, and seconds are the units that are used to measure time.

Answer: There are 86400 seconds in a day.

Let's convert 24 hours into seconds.

Explanation:

We know that,

1 day = 24 hours

In 1 hour there are 60 minutes and in 1 minute there are 60 seconds.

Therefore, number of seconds in 1 hour = 60 × 60 = 3600 seconds

Now, number of seconds in 24 hours or in a day = 24 × 3600 = 86400 seconds

Thus, there are 86400 seconds in a 24-hour day.
