Converting Units of Time

1 minute = 60 seconds

1 hour = 60 minutes

1 day = 24 hours

1 week = 7 days

1 month = 30 days = 4 weeks (approximately)

1 year = 12 months = 365 days = 52 weeks (approximately)

1 decade = 10 years

1 century = 10 decades = 100 years

1 millennium = 100 decades = 1000 years

 

To convert a larger unit of time to a smaller unit of time, multiply. 

To convert a smaller unit of time to a larger unit of time, divide.

 

For example: To find the number of minutes in 2 hours and 16 minutes,

first convert the hours into minutes by multiplying number of hours by 60.

 

2 × 60 = 120 

 

So, 2 hours = 120 minutes

 

Now, 

2 hours and 16 minutes = 120 minutes + 16 minutes = 136 minutes

 

So, there are 136 minutes in 2 hours and 16 minutes.
