36sec

3,600 seconds in an hour. That's 60 × 60.

💡Easy to remember: 36 × 100 = 3,600!

60 minutes × 60 seconds = 3,600 seconds. Each minute has 60 seconds, and an hour has 60 minutes.

💡Think of it as 60² (60 squared).

1 minute = 60 seconds | 1 hour = 3,600 seconds | 1 day = 86,400 seconds | 1 week = 604,800 seconds

💡86,400 = 24 × 3,600 (hours in a day × seconds per hour).

1/2 hour = 1,800 sec | 1/4 hour = 900 sec | 1/10 hour = 360 sec | 1 sec = 0.000278 hours

💡15 minutes = 900 seconds is useful for timers.

Multiply hours by 3,600. Example: 2.5 hours × 3,600 = 9,000 seconds.

Divide seconds by 3,600. Example: 7,200 seconds ÷ 3,600 = 2 hours.

86,400 seconds (24 hours × 3,600 seconds per hour).
