9. CONVERT TIME
MEASURES FROM
SMALLER
TO LARGER UNITS,
AND VICE VERSA

10. Time conversions refer to the
process of changing a time
measurement from one unit to
another, usually to make it
easier to understand or to
compare different time intervals.
This can involve converting
smaller units of time to larger
units or vice versa.

11. • 60 seconds = 1 minute
• 60 minutes = 1 hour
• 24 hours = 1 day
• 7 days = 1 week
• 4 weeks (approximately)
= 1 month
• 12 months = 1 year

12. Example 1:
2 minutes = ___ seconds
• How many seconds are there in 1
minute? 60 seconds
• Therefore, how many seconds are
there in 2 minutes? 120 seconds
• How did you get the correct
answer? 2 x 60 seconds = 120 seconds

13. Example 2:
3 weeks = ___ days
• How many days are there in 1
week? 7 days
• Therefore, how many days are there
in 3 weeks? 21days
• How did you get the correct
answer? 3 x 7 days = 21 days

14. Example 3:
12 hours = ____ minutes
Solution: Since there are 60 minutes in
1 hour, 12 x 60 minutes = 720 minutes
Example 4:
13 days = ___ hours
Solution: Since there are 24 hours in 1
day, 13 x 24 hours = 312 hours

15. Example 5:
3 months = ______weeks
Solution: Since there are around 4
weeks in 1 month, 3 x 4 weeks = 12
months
Example 6:
20 years = ____ months
Solution: Since there are 12 months in
1 year, 20 x 12 = 240 months

16. Directions: Convert the
following larger units to smaller
units.
