2 The Metric StaircaseA staircase is an excellent model of how the prefixes of metric units relate to each other.

5 Length Larger The standard unit of length is the meter. Kilometer km Hectometer hmDekameter dkmMeter mDecimeter dmCentimeter cmLargerMillimeter mmThe standard unit of length is the meter.
6 Mass Larger The standard unit of mass is the gram. Kilogram kg Hectogram hgDekagram dkgGram gDecigram dgCentigram cgLargerMilligram mgThe standard unit of mass is the gram.
7 Volume Larger The standard unit of volume is the liter. Kiloliter kl Hectoliter hlDekaliter dklLiter lDeciliter dlCentiliter clLargerMilliliter mlThe standard unit of volume is the liter.
8 The Metric Staircase Kilo Hecto Deka Ones/Base Deci Centi Milli The staircase also tells us which way to move the decimal. As the unit gets smaller, you shift the decimal to the right. As the unit gets larger, the decimal shifts to the left.
9 The Metric Staircase Kilo Hecto Deka Ones/Base Deci Centi Milli The metric staircase is easy to use because each unit differs from the next by a factor of 10.Units get larger as you climb. Units get smaller as you descend.
10 The Metric Staircase Kilo Hecto Deka Ones/Base Deci Centi Milli When converting between units, move the decimal one place for every step taken. Move it in the direction shown on the staircase. If there is not a number in the moved place, place a zero in the spot.
11 kmhmdkmmdmcmmmLet’s use a line to represent a distance of a kilometer.1 km=10 hm=100 dkm=? m = ? dm = ?cm= ? mm
12 . Sample Problem: 7.359 m = ???? cm 735.9 cm km hm dkm m dm cm mm To get from m to cm, we must take 2 steps to the right. Therefore, we must shift the decimal two places to the right..Answer:735.9 cm7.359 m = cm
13 . . Sample Problem: 1200 m = ???? km 1.2 cm km hm dkm m dm cm mm Answer:1.2 cm
