How Many Seconds Are in an Hour?

1 hour has 3,600 seconds.

Seconds in an hour calculation

We know that 1 hour is 60 minutes.

And we know that 1 minute is 60 seconds.

So if we multiply all that through, we have:

= 60 minutes per hour x 60 seconds per minute

= 3,600 seconds per hour (3,600 seconds per 60 minutes)

Of course, armed with this knowledge, you can calculate how many seconds there are…

– per day (per 24 hours)

– per week

– per month

– per year

– per decade

– per century…

…and virtually every other expanse of time.
