2 Making conversionsStep 1: Write down a conversion factor between the two types of things you are comparing. If you don’t know it, look it up. Step 2: Use “railroad tracks” or “factor-label” method to set up conversion formula. If you need to make multiple conversions, set each one up one at a time. Step 3: Multiply across the top, multiply across the bottom, divide top by bottom. Answer. Include your final units.
3 Practice 240 Mm = __________ m 736 nm = ___________ m 1 Mm = 106 m Ans: 7.36 x 10-7 m
4 More practice 6.42 m = ___________ km 42 m = ___________ µm Ans: 6.42 x 103 kmAns: 4.2 x 107 µm
5 Still more practice (the “hard” ones) 12.3 Gm = _____________ pm 60,000 fm = _____________ km1 Gm = 109 m1 m = 1012 pm1 fm = m1000 m = 1 kmAns: 6 x km
7 PreAP Students: If you don’t know the conversion factor look it up: In a bookOn the internet (wikipedia is good)On a website:“MultiConvert” app for smartphoneIf you use the website or the app: don’t cheat. Don’t go straight to the result, even if you can. This does you no good on your upcoming test. Just use it to find the conversion factors. You could also use it to check your work
