How to Convert Units of Measure for Time
Content
Corps

In order to convert units of measure for time, it is important to understand the relationships or equivalencies between these units of measure.

Convert 5 weeks to days (d).

  1. I identify the equivalency between the units of measure.

    For a reminder, I can refer to the concept sheet Units of Time.

 1 week = 7 days

  1. Since there are 5 weeks, I add 7 days 5 times or I multiply 5 by 7 days.

7 d + 7 d + 7 d + 7 d + 7 d = 35 d
or
5 × 7 d = 35 d

5 weeks is equivalent to 35 days.

Convert 4 hours (hr) 35 minutes (min) into minutes.

  1. I identify the equivalency between the units of measure.

    For a reminder, I can refer to the concept sheet Units of Time.

1 hour = 60 minutes

  1. Since there are 4 hours, I add 60 minutes 4 times or I multiply 4 by 60 minutes.

60 min + 60 min + 60 min + 60 min = 240 min
or
4 × 60 min = 240 min

  1. Then, I add the remaining 35 minutes.

240 min + 35 min = 275 min

4 hours and 35 minutes is equivalent to 275 minutes.

Convert 424 seconds (s) into minutes (min).

  1. I identify the equivalency between the units of time.

    For a reminder, I can refer to the concept sheet Units of Time.

60 s = 1 min

  1. Then, I find how many times 60 s (1 min) goes into 424 s.

    60 s goes into 424 s 7 times, so there is 7 full minutes (420 s) in 424 s.

60 × 5 = 300
60 × 6 = 360
60 × 7 = 420
60 × 8 = 480

  1. To find the number of remaining seconds, I calculate the difference between 424 s and 420 s.

424 s - 420 s = 4 s

424 s is equivalent to 7 min and 4 s.
