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.
