Metric Conversions
These show how to go from one metric unit to another.

2. Types of units
Base units – can be measured directly Derived – are gotten by a formula or mathematical operation.

3. There are 3 Systems 1. English System ex: inches, pounds, gallon
Metric system (need to know) –
A. base units
distance-meter (m)
mass – grams (g)
time – seconds (s)
temperature – Kelvin (K)
amount of substance (number of) – mole (mol)
intensity of light – candela (cd)
B. Common derived unit
volume – liter (L)

4. International System
The major difference for this class regarding units between the SI system and metric system is the unit for mass is kilogram (kg).

6. Example: Convert 1.00 meter to a kilometer.
1. Place the decimal of the given number (1.00 meter) at the place that matches the starting unit.
Mega (M)
micro (µ)
Hecto (h)
deka(da)
nano (n)
De`ci (d)
milli (m)
centi (c)
Kilo (K)
Base I
M _ _ k h da B d c m _ _ µ
1.00

7. 2. Find the prefix for the number that you want to convert it to.
M _ _ k h da B d c m _ _ µ
1.00

8. 3. Count the number of places that you will need to move the decimal.
M _ _ k h da B d c m _ _ µ
1.00
So the final answer is .001 km.

9. Example 2: Convert 0.0003cm to km
M _ _ k h da B d c m _ _ µ
Line up the decimal at the centi place.

10. Find the unit to convert to, (kilo in this example).
M _ _ k h da B d c m _ _ µ
The decimal is moved 5 places to the left so that is what you do for the number.
The answer is

11. Example 3: Convert 3.08g to µg.
M _ _ k h da B d c m _ _ µ
3.08

12. Find the prefix you are converting to.
M _ _ k h da B d c m _ _ µ
3.08
We then have to do that to the number.
The final answer is µg.

13. Practice problems Convert the following: 400 meters to millimeters
5800 liters to hectoliters
6120 nanograms to milligrams
