2 Base Units What measures what Length/Distance meter km hm dam m dm cm mmWeight/mass gramkg hg dag g dg cg mgVolume literkL hL daL L dL cL mL
3 Metric To Metric Conversion Step One: Line up the metric units from largest to smallest: km hm dam m dm cm mmkl hl dal l dl cl mlkg hg dag g dg cg mgStep Two:Count the number of steps from the unit you have to the unit you want.Step Three: Move the decimal point the direction you moved toget from one unit to the other that many steps.
4 4.5 L = mlStep One: Line up the metric units from largest to smallest:kl hl dal l dl cl mlStep Two: Count the number of steps from the unit you have to the unit you want in your answer.To get from liters to milliliters on the chart, it takes three steps to the right.Step Three: Move the decimal point the same direction you moved.So the decimal point must be moved three steps to the right as well.4.5 L = 4,500 ml
5 Metric to Metric Conversion Practice problemsa) 5 cm = _______mmb) 12.8 dg = ______mgc) 14,450 mm = _____md) km = _______me) 2000 ml = ________ L
6 Standard to Metric Conversion Formulas Lengthinches x 2.54 = cm (centimeters)feet x = m (meters)miles x 1.6 = km (kilometers)Weightpounds 2.2 = kg (kilograms)ounces x 28 = g (grams)Volumegallons x 3.8 = L (liters)fluid ounces x 30 = ml (milliliters)
7 How many liters are in 2 gallons Standard to Metric Conversion How many liters are in 2 gallonsof milk?gallons x 3.8 = L (liters)2 gallons x 3.8 = 7.6 LGot milk??
8 YUMMMMMM! The worlds largest candy bar weighs 5,500 pounds. How many kilograms?pounds 2.2 = kg (kilograms)5,500 lbs 2.2 = 2,500 kgYUMMMMMM!
9 Just DO IT !3 feet to meters12 inches to centimeters1 ounce to grams6 fluid ounces to milliliters3 ft x = 0.9 m12 in x 2.54 = 30.5 cm1 oz x 28 = 28 grams6 fl oz x 30 = 180 ml
