Dimensional Analysis Converting the Big Kids Way!
So Go Back to Conversions 1 m = __________ mm m = 1000 mm 1 m = mm.
Other Conversions 100 cm = 1 m 1000 g = 1 kg 10 dL = 1 L 100 cm = 1 1 m 1 m = cm OR
Periodic Table Find the conversions on your periodic table
Dimensional Analysis First know what you START WITH! –Dont forget units –Dont lose decimal point Second know what you END WITH –It is usually unknown except for the unit.
Put it together Start: 360 s End: x ms 360 s x (some conversion) (rest of conversion)
Put it together Think: Which gets rid of s So you have to use SSSS S x S SSSS OR
Put it together Start: 360 sEnd: x ms 360 s x (some conversion) = something s SSSS
Put it together Start: 360 sEnd: x ms We want ms so it goes in the numerator 360 s x something ms something s Find the conversion on your periodic table
Put it together Periodic Table: 1 ms = 1 x s 1 ms. 1 x s 1 x s 1 ms OR
Put it together Start: 360 sEnd: x ms End: x ms Which works better? –3–360 s x –3–360 s x 1 ms. 1 x s 1 ms
Put it together 360 s x Put it in your calculator 360,000 ms 1 ms. 1 x s
Steps to Dimensional Analysis 1.Label start (with unit) 2.Label end (with unit) 3.Identify conversion factor 4.Set up railroad 5.Write answer 6.Sig Fig final answer

SI Measurement. International System of Units Metric system is now revised and named as the International System of Units (SI), as of 1960 It has simplicity,
Chapter 1 Matter and Measurement. Classification of Matter Check your neighbors understanding for the following words and organize them into a flow chart:
Atomic, molecular, and formula masses Atomic weight? So what is the unit for atomic mass? An analogy for atomic mass An "atomic weight" experiment Avogadro's.
The Metric System. Why do we use/have to learn about the Metric System? Almost all the countries in the world use metric system. Other countries companies.
3.3 Solving equations with variables on both sides. When you have variables on both sides, move them to one side. Usually we move the variable to the.
UNIT II.1 Unit Conversions. II.1 UNIT CONVERSIONS You MUST learn and use the unit conversion method (not your own method!) A CONVERSION FACTOR: is a fractional.
