2 Prefix definitionRemember that a prefix by definition means a word bit that goes in front of a base word to alter its meaning.Ex. anti-warAnti means “against”Therefore anti-war means “against war”Ex. ProlifePro means “for”…
3 Metric Base Units Base units are the standard unit of measurement Length = meter (m)Mass = gram (g)Volume = Liter (L)
4 Prefix Sequence Kilo (k) Hecto (h) Deca (da or D) Base units Deci (d) Centi (c)Milli (m)KingHectorDiedbyDrinkingChocolateMilk
5 Any time you see a letter by itself, it is a base unit! Sequence Chartk h D b d c mkm hm Dm m dm cm mmkg hg Dg g dg cg mgkL hL DL L dL cL mLAny time you see a letter by itself, it is a base unit!
6 Using the Chart k h D b d c m When given a number, such as 3 meters, you must put the decimal at the end.3 m = 3.0 m*Each letter represents a decimal place.
7 Using the Chart cont’d k h D b d c m When asked to convert 3 meters (3.0 m), find your starting point on the chart.Meter, m, is a base unit.
8 Using the Chart cont’d k h D b d * c m Convert 3 meters (3.0 m) to centimeters.Remember that centimeters is cm.Locate where you are headed on the chart.Count the letters between the two areas.
9 Using the Chart cont’d k h D b d c m There are two letters between the two areas.Each letter represents a decimal place.We are moving two decimal places.We are moving from meters (b) to centimeters (c), which is left to right.
10 Our answer is… Convert 3 meters to centimeters. 3.0 m = ___ cm Move the decimal to the right two places3.0 m = = 300. cmThe final answer is 3 m = 300 cm
11 Now try a few others 25 g = ___ kg 47 cm = ___ mm 1,030 mm = ___ m 67 kg = ___ g455 mL = ___ L25 g = .025 kg47 cm = 470 mm1,030 mm = 1.03 m67 kg = 67,000 g455 mL = .455 L
