8. Metric System Conversions
  Length (m) Mass (g) Volume (L)
1000 m= 1 km g= 1 kg L= 1 kL
100 m= 1 hm g= 1 hg L= 1 hL
10 m= 1 dam g= 1 dag L= 1 daL
1 m= 10 dm g= 10 dg L= 10 dL
1 m= 100 cm g= 100 cg L= 100 cL
1 m= 1000 mm g= 1000 mg L= 1000 mL

9. Dimensional Analysis (1 Step)
You must use a conversion factor!!! How many milliliters are in liters?
0.005𝐿 1 ( 𝑚𝐿 1 𝐿 )= 5 mL

10. Dimensional Analysis (2 Step)
If you do not have a conversion factor between the given unit and the one you are looking for, you must do two conversions.
How many milliliters are in kiloliters?
0.005𝑘𝐿 1 ( 1000𝐿 1 𝑘𝐿 ) ( 𝑚𝐿 1 𝐿 )= 5000 mL

11. Dimensional Analysis (1 Step)
230 mm =___m
67 L= __daL
98,057 g= __dg
5.40x10-7 kg= __g
4.77x10-2 hm= __m
67𝐿 1 ( 1 𝑑𝑎𝐿 10 𝐿 )= 6.7 daL
98057𝑔 1 ( 10 𝑑𝑔 1 𝑔 )= dg
5.40𝑥10−7 𝑘𝑔 1 ( 𝑔 1 𝑘𝑔 )= 5.4x10-4 kg
4.77𝑥10−2 ℎ𝑚 1 ( 100 𝑚 1 ℎ𝑚 )= 4.77 m

12. Dimensional Analysis (2 Step)
230 mm =__km
67 hL= __daL
98,057 dg= _dag
5.40x10-7 kg= _mg
4.77x10-2 hm= _cm
230𝑚𝑚 1 ( 1𝑚 1000𝑚𝑚 )( 1𝑘𝑚 1000𝑚 )= 2.3x10-4 km
67ℎ𝐿 1 ( 100𝐿 1ℎ𝐿 )( 1 𝑑𝑎𝐿 10 𝐿 )= 670 daL
98057𝑑𝑔 1 ( 1𝑔 10𝑑𝑔 )( 1 𝑑𝑎𝑔 10 𝑔 )= dag
5.40𝑥10−7 𝑘𝑔 1 ( 1000𝑔 1𝑘𝑔 )( 1000𝑚𝑔 1𝑔 )= 0.54 mg
4.77𝑥10−2ℎ𝑚 1 ( 100𝑚 1ℎ𝑚 )( 100𝑐𝑚 1 𝑚 )= 477 cm
