2 Why science ALWAYS uses metric Two different groups of scientists were working on the calculations to send a probe to Mars.The American team did their calculations in the English standard and the other team did it in the metric system (OOPS!)It cost the space program 125 million dollarsIt cost the scientists their time
3 The Metric SystemThe metric system is an internationally standardized system of units of measurement.The metric system is based on a base unit and prefixes.
4 Prefixes Kilo - 1000 k Hecto - 100 h Deca - 10 da none 1 none Deci dCenti cMilli m
5 Base Units Length: Meter Mass: Gram Volume: Liter Time: Second (DOES NOT USE PREFIXES!)
6 Length Metric Units of Length Kilometer (km) = 1000 m Hectometer (hm) = 100 mDecameter (dam) = 10 mMeter (m) = 1 mDecimeter (dm) = 0.1 mCentimeter (cm) = 0.01 mMillimeter (mm) = m
7 Mass Metric Units of Mass Kilogram (kg) = 1000 g Hectogram (hg) = 100 gDecagram (dag) = 10 gGram (g) = 1 gDecigram (dg) = 0.1 gCentigram (cg) = 0.01 gMilligram (mg) = g
8 Volume Metric Units of Capacity Kiloliter (kL) = 1000 L Hectoliter (hL) = 100 LDecaliter (daL) = 10 LLiter (L) = 1 LDeciliter (dL) = 0.1 LCentiliter (cL) = 0.01 LMilliliter (mL) = L
9 Conversions within the Metric System To convert units within the metric system, write the prefixes in order from largest to smallestk h da d c mTo convert from a smaller unit to a larger unit, move to the leftTo convert from a larger unit to a smaller unit, move to the right
10 Ex: Convert 1600 cm to m km hm dam m dm cm mm Move 2 places to the left to get from cm to mTherefore, move the decimal point in 1600 two places to the left to convert from cm to m1600 cm = m
11 Ex: Convert 2 kL to L kL hL daL L dL cL mL Move 3 places to the right to get from kL to LTherefore, move the decimal point in 2 three places to the right to convert from kL to L2 KL = 2000 L
12 Ex: Convert 45 cm to km km hm dam m dm cm mm Move 5 places to the left to get from cm to kmTherefore, move the decimal point in 45 five places to the left to convert from cm to km45 cm = km
