How we split up time
Time is made of small units. We use seconds, minutes, hours, days, weeks, months and years. A bigger unit is always made of smaller ones.
Key idea
1 minute = 60 seconds · 1 hour = 60 minutes · 1 day = 24 hours · 1 week = 7 days · 1 year = 12 months
Changing units
To change a bigger unit into a smaller unit, we multiply. For example, to change hours into minutes, multiply by 60.
Worked example
How many minutes are there in 2 hours?
1 hour = 60 minutes, so 2 hours = 2 × 60 = 120 minutes.
Remember
- Half an hour = 30 minutes.
- A quarter of an hour = 15 minutes.
- A bigger unit always holds more small parts.
