To convert hours to seconds, use this rule:
Multiply the number of hours by 3,600:
Examples:
Tip: This works because 1 hour = 60 minutes and 1 minute = 60 seconds, so 60 × 60 = 3,600.
There are 3,600 seconds in 1 hour.
That comes from 60 minutes per hour and 60 seconds per minute: 60 × 60 = 3,600.
Use this simple formula:
seconds = hours × 3,600
If you have a decimal hour, the same formula works.
Multiply hours by 3,600:
2 × 3,600 = 7,200 seconds
Half an hour is 0.5 hours. Multiply by 3,600:
0.5 × 3,600 = 1,800 seconds
Multiply 1.25 by 3,600:
1.25 × 3,600 = 4,500 seconds
This also matches 1 hour (3,600) plus 15 minutes (900).
A day has 24 hours. Multiply by 3,600:
24 × 3,600 = 86,400 seconds
Convert each part, then add them:
Total: (hours × 3,600) + (minutes × 60) + seconds
Example: 1 hour, 2 minutes, 3 seconds
= (1 × 3,600) + (2 × 60) + 3
= 3,600 + 120 + 3
= 3,723 seconds
Divide seconds by 3,600:
hours = seconds ÷ 3,600
Example: 7,200 seconds ÷ 3,600 = 2 hours
Time units are built on base-60 steps:
So one hour is 60 × 60 seconds, which equals 3,600.
Yes. The math stays the same:
seconds = hours × 3,600
Example: -2 hours × 3,600 = -7,200 seconds
Convert 1.5 hours to seconds:
1.5 × 3,600 = 5,400 seconds
You can also do it in parts:
1 hour = 3,600 seconds, 30 minutes = 1,800 seconds, total = 5,400 seconds
Use 3,600 seconds per hour.
For a rough estimate, round the hours first, then multiply by 3,600. For exact results, use the full number, including decimals.
