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

  • Remember key conversions like 60 seconds = 1 minute and 24 hours = 1 day.
  • 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.

Learn with an example

⌛How many days are in 3 weeks?

 ______ days

There are 7 days in a week. To find out how many days are in 3 weeks, multiply 7 by 3:

There are 21 days in 3 weeks.

⌛How many seconds are in a minute?

 _______ seconds

There are 60 seconds in a minute.

⌛Convert to 60 minutes = ​______ hours

1 hour is 60 minutes.
