2 ~King Henry Died unexpectedly Drinking Chocolate Milk~ Unlike our English system of measurement with its feet and inches, quarts and gallons,the metric system is very orderlyAll variations of the units of measure are really just the units multiplied by powers of 10.Converting to larger or smaller unit measurements is a matter of multiplying or dividing by 10, 100, 1000 and so forth.This can be simply accomplished by moving the decimal place to the left or right the appropriate number of spaces, as we will soon see.
3 The Basic Units of Metric Measure Distance = measured in meters, “m”Volume = measured in liters, “l”Mass = measured in grams, “g”King Henry Died Unexpectedly Drinking Chocolate Milk…
4 King Henry’ Died Unexpectedly Drinking Chocolate Milk!!!!!!!!!! To help you gain a basic understanding of their relative size, it is useful to learn to associate familiar everyday items of similar measurement with the basic units.King Henry Died Unexpectedly Drinking Chocolate MilkA meter is approximately equal to the length of a yardstick.A liter is approximately equal to the volume of a quart.A gram is approximately equal to the weight of a paper clip.King Henry Died Unexpectedly Drinking Chocolate Milk!!!
5 What does King Henry have to do with all this? Well... nothing actually, but this silly sentence IS a mnemonic device, a memory tool, to help you remember the relationships between the variations of these basic units.[K]ing [H]enry [D]ied (u)nexpectedly [d]rinking [c]hocolate [m]ilk

7 These prefixes are based on powers of 10… What does this mean?… From each prefix every “step” is either:10 times largeror10 times smallerFor exampleCentimeters are 10 times larger than millimeters1 centimeter = 10 millimeters10
8 1 cm = 10 mmCentimeters are 10 times larger than millimeters so it takes more millimeters for the same length1 centimeter = 10 millimetersExample not to scale40411 mm40411 cm
9 For each “step” to right, you are multiplying by 10 For example, let’s go from a base unit to centi1 liter = 10 deciliters = 100 centiliters2 grams = 20 decigrams = 200 centigramsKiloHectoDecaUnitdecicentimilli

12 Metric SystemSummaryBase units in the metric system are meter, liter, gramMetric system is based on powers of 10For conversions within the metric system, each “step” is 1 decimal place to the right or leftUsing the diagram below, converting to the right, moves the decimal to the right and vice versaKiloHectoDecaUnitdecicentimilli
