1 minute = 60 seconds
1 hour = 60 minutes
1 day = 24 hours
Steps to convert hours to seconds:
Step 1: Let us first convert hours to minutes.
Step 2: Then, convert minutes to seconds.
Example:
1. Convert 1 hour to seconds.
Solution:
1 hour = 60 minutes
= 60 \times 1 minute
= 60 \times 60 seconds [Since 1 minute = 60 seconds]
= 3600 seconds
Therefore, 1 hour = 3600 seconds.
2. Convert 7266 seconds to hours.
Solution:
Let us do the above procedure in reverse.
First convert seconds to minutes.
60 seconds = 1 minute
1 second = minute
7266 seconds = minutes
Now, convert minutes to hours.
60 minutes = 1 hour
1 minute = hour
minutes = hour
7266 seconds = 2 hours + 66 seconds
= 2 hours + 60 seconds + 6 seconds
= 2 hours + 1 minute + 6 seconds
Therefore, 7266 seconds = 2 hours 1 minute 6 seconds.
Steps to convert day to seconds:
Step 1: Let us first convert day to hours.
Step 2: Now, convert hours to minutes.
Step 3: Finally, convert minutes to seconds.
Example:
1. Convert 1 day to seconds.
Solution:
1 day = 24 hours
= 24 \times 1 hour
= 24 \times 60 minutes [Since 1 hour= 60 minutes]
= 1440 minutes
= 1440 \times 60 seconds
= 86400 seconds
Therefore, 1 day = 86400 seconds.
