  2. Not in notes You and your friends want to have a movie marathon on . All three movies last a total of 390 min. How many hours will it take to watch all three movies? = 6.5 min How do we get the unit to change to hours? We need to use dimensional analysis.

  3. Not in notes Process using unit ratios (conversion factors) to convert between units. Dimensional analysis - Unit Ratio (conversion factors)- A ratio where the numerator and denominator are equivalent measurements. Conversion factors and dimensional analysis make comparing different units much easier. These conversions are necessary in many calculations in your physical science and chemistry classes.

  4. Fill in the Missing Numbers 12 1 ft = ____ in 1 m = ____ cm 1 lb = ____ oz 1 min = ____ sec 1 hr = ____ min 1 day = ___ hrs 1 yr = ____ mo 1 yr = ___ wks 1 km =_____ m 1 mi = _____ yd 1 yd = ___ ft 1 cm = ___ mm 1 gal = ____ qt 1 qt = ___ pt 1 pt = ___ c 1 wk = ___days 1000 100 1760 16 3 60 10 60 4 24 2 12 2 52 7 16 1000 1 c = _____ fl oz 1 T = _____ lb 1 kg = ____ g 1 L = ______ mL 1 yr = ____ mo 1 g = ____ mg 2000 12 1000 1000

  5. Not in notes Dimensional analysis process Unit you have X Conversion factor = Unit you want Remember : we can cancel with multiplying fractions we can do the same with units. 1 1 You and your friends want to have a movie marathon.
