Convert time units
key notes :
🎯 1. Understanding Time Units
- 1 minute (min) = 60 seconds (sec)
- 1 hour (hr) = 60 minutes
- 1 day = 24 hours
- 1 week = 7 days
- 1 year = 12 months or 365 days (366 in a leap year)
- 1 decade = 10 years
- 1 century = 100 years
⏳ 2. Conversion Examples
- Minutes to seconds:
Example: 5 minutes = 5 × 60 = 300 seconds - Hours to minutes:
Example: 3 hours = 3 × 60 = 180 minutes - Days to hours:
Example: 2 days = 2 × 24 = 48 hours - Weeks to days:
Example: 3 weeks = 3 × 7 = 21 days - Years to months:
Example: 2 years = 2 × 12 = 24 months
🔄 3. Reverse Conversions
- Seconds to minutes:
Example: 120 seconds ÷ 60 = 2 minutes - Minutes to hours:
Example: 150 minutes ÷ 60 = 2 hours 30 minutes - Hours to days:
Example: 48 hours ÷ 24 = 2 days
📌 4. Real-Life Application
- Cooking: Convert minutes to seconds for precise timing.
- Travel: Calculate hours to minutes for trip duration.
- Sports: Measure race times in seconds and minutes.
🧠 5. Quick Tips for Success

- Use multiplication for bigger units (e.g., days to hours).
- Use division for smaller units (e.g., seconds to minutes).
- Practice with word problems to build confidence.
