The METRIC SYSTEM & CONVERSIONS MSJC ~ San Jacinto Campus Math Center Workshop Series Janice Levasseur
The Metric System • The metric system is an internationally standardized system of units of measurement. • The metric system is based on a base unit and prefixes.
Prefixes • • • • • • • Kilo Hecto Deca Deci Centi Milli - 1000 100 10 1 0.1 0.01 0.001 k h da d c m
Length • The basic unit of length in the metric system is the meter (m) • Metric Units of Length – – – – – – – Kilometer (km) = 1000 m Hectometer (hm) = 100 m Decameter (dam) = 10 m Meter (m) = 1 m Decimeter (dm) = 0.1 m Centimeter (cm) = 0.01 m Millimeter (mm) = 0.001 m
Mass • Weight is a measure of how strongly gravity is pulling on an object (decreases as elevation increases) • Mass is the amount of material in an object (doesn’t change) • Note: on Earth, weight and mass are used interchangeably
Mass • The basic unit of mass in the metric system is a gram (g) • 1 g = mass of water in a cube that measures 1 cm x 1 cm x 1cm • Metric Units of Mass – – – – – – – Kilogram (kg) = 1000 g Hectogram (hg) = 100 g Decagram (dag) = 10 g Gram (g) = 1 g Decigram (dg) = 0.1 g Centigram (cg) = 0.01 g Milligram (mg) = 0.001 g
Capacity • Liquid substances are measured in units of capacity. • The basic unit of mass in the metric system is a liter (L) • 1 L = capacity of a cube that measures 10 cm x 10 cm x 10 cm • Metric Units of Capacity – – – – – – – Kiloliter (kL) = 1000 L Hectoliter (hL) = 100 L Decaliter (daL) = 10 L Liter (L) = 1 L Deciliter (dL) = 0.1 L Centiliter (cL) = 0.01 L Milliliter (mL) = 0.001 L
Conversions within the Metric System • To convert units within the metric system, write the prefixes in order from largest to smallest k h da d c m • To convert from a smaller unit to a larger unit, move to the left • To convert from a larger unit to a smaller unit, move to the right
Ex: Convert 1600 cm to m • km hm dam m dm cm mm • Move 2 places to the left to get from cm to m • Therefore, move the decimal point in 1600 two places to the left to convert from cm to m 1600 cm = 16.00 m
Ex: Convert 2 kL to L • kL hL daL L dL cL mL • Move 3 places to the right to get from kL to L • Therefore, move the decimal point in 2 three places to the right to convert from kL to L 2 KL = 2000 L
Ex: Convert 241 g to mg • kg hg dag g dg cg mg • Move 3 places to the right to get from g to mg • Therefore, move the decimal point in 241 three places to the right to convert from g to mg 241 g = 241,000 mg
Ex: Convert 3 mL to L • kL hL daL L dL cL mL • Move 3 places to the left to get from mL to L • Therefore, move the decimal point in 3 three places to the left to convert from mL to L 3 mL = 0.003 L
Ex: Convert 45 cm to km • km hm dam m dm cm mm • Move 5 places to the left to get from cm to km • Therefore, move the decimal point in 45 five places to the left to convert from cm to km 45 cm = 0.00045 km
Ex: Convert 5.4 kg to dg • kg hg dag g dg cg mg • Move 4 places to the right to get from kg to dg • Therefore, move the decimal point in 5.4 four places to the right to convert from kg to dg 5.4 kg = 54000 dg
