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)

Milli (m)

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
