1 These show how to go from one metric unit to another. Metric ConversionsThese show how to go from one metric unit to another.
2 Types of unitsBase 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 unitsdistance-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 unitvolume – liter (L)
4 International SystemThe 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)BaseIM _ _ k h da B d c m _ _ µ1.00
7 2. Find the prefix for the number that you want to convert it to. M _ _ k h da B d c m _ _ µ1.00
8 3. Count the number of places that you will need to move the decimal. M _ _ k h da B d c m _ _ µ1.00So the final answer is .001 km.
9 Example 2: Convert 0.0003cm to km M _ _ k h da B d c m _ _ µLine 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 _ _ µThe 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 _ _ µ3.08
12 Find the prefix you are converting to. M _ _ k h da B d c m _ _ µ3.08We 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 hectoliters6120 nanograms to milligramscentimeters to kilometers
14 Homework: Convert each to the unit given. g to Kghg to cgcm to metercm to µmhg to gg to Mgdam to dmL to mLcm to mmL to hLMm to Kmmg to gµm to mKL to ML8. 2,000,000 mm to kmdL to L
