1. Metric System
(it’s easier than you think!)

2. Easier Because:
 It’s based on 10’s
 It’s based on universally found items
 Ex: One milliliter is equal to one gram of
water

3. Basic Units (and abbreviations)
 Mass: gram (g) (the amount of matter in something)
 Distance: meter (m) (the length between two points)
 Volume: Liter (L) (the amount of space something
takes up)
 Time: second (s) (how long an event takes to
happen)
 Temperature: degrees Celsius (°C) (the average
speed of the molecules in something)

4. Prefixes
 These are the words that come before the
basic units
 They show how much there is
 Example kiloliter would be abbreviated to kL
 Kilo (or k) means 1000
 So, you have how many liters in one kiloliter?

5. The ladder method
 Used to convert among prefixes:
Kilo (K)
(King) Hecto (H)
(Henry) Deca (da)
(Died) Basic Unit
(by)
Deci (d)
(Drinking)
Centi (c)
(chocolate
Milli (m)
(Milk)

6. Try these examples:
 100Kg= ____g
 45 m= ____cm
 45 cm= ____m
 39.67 ms=___ s What is bigger: 1000 meters
or 1 Kilometer?
 What is bigger: 55,000 liters or 56,000,000
milliliters?
