Conversion Between Units of Time
- 1 minute = 60 seconds
- 1 hour = 60 minutes
- 1 day = 24 hours
- 1 week = 7 days
- 1 month = 30/31 days
- 1 year = 365/366 days
Example 1: Convert 3 Hours 45 Minutes to Seconds
Step 1: Convert hours to minutes. 1 hour = 60 minutes, so 3 hours = 3 × 60 = 180 minutes.
Step 2: Add minutes. 180 minutes + 45 minutes = 225 minutes.
Step 3: Convert minutes to seconds. 1 minute = 60 seconds, so 225 minutes × 60 = 13,500 seconds.
Answer: 3 hours 45 minutes = 13,500 seconds.
Example 2: Convert 2 Days 12 Hours to Minutes
Step 1: Convert days to hours. 1 day = 24 hours, so 2 days × 24 hours = 48 hours.
Step 2: Add hours. 48 hours + 12 hours = 60 hours.
Step 3: Convert hours to minutes. 60 hours × 60 = 3,600 minutes.
Answer: 2 days 12 hours = 3,600 minutes.
