SI Unit Conversions Convert 3450 cm to km. 3450 cm 1 km 105 cm = 3450 x 10 -5 km or 3. 45 x 10 -2 km Convert 0. 0036 g to mg. 0. 0036 g 106 mg 1 g = 0. 0036 x 106 mg or 3. 6 x 103 mg Convert 8. 9 x 10 -8 s to ps. 8. 9 x 10 -8 s 1012 ps 1 s = 8. 9 x 104 ps

Practice with Conversion • Convert the following: 23. 2 m = ______ cm 93. 71 m = ______ km 920, 000 µm = _____m 3. 6 x 10 -11 ML = _____ L 1. 41 x 1014 pg = ____g 16. 0 ns = ____ s

Practice with Dimensional Analysis In Raiders of the Lost Ark, Indiana Jones tried to remove a gold idol from a boobytrapped pedestal. He replaces the idol with a bag of sand. If the idol has a mass of 2. 00 kg, how many litres of sand must he place on the pedestal to keep the mass sensitive booby-trap from activating? (Density of sand is 3. 00 g/cm 3)

Practice with Dimensional Analysis • At a given point in its orbit, the moon is 2. 4 x 105 miles from earth. How long does it take light from a source on earth to reach a reflector on the moon and then return to earth? (speed of light is 3. 0 x 108 m/s) Conversions: 1 mi- 5280 ft 2. 54 cm = 1 in.
