**Metric System**Unit 2**History**• Inch-pound measuring system was adopted early in this country for two principal reasons • Most of our trade was with England where the inch-pound system was in use. • While the metric system was more uniform in its application to weights and measures, it was not firmly established in any nation including France where it had its beginning • Today the International (SI)Metric System is in use in most nations of the world and the US is moving toward the metric system**Length**International System of Units (SI) Metric • Foot (base) • Smaller • Inches • Fractions • Larger than a foot • Yard • Mile • Meter • Smaller than a meter • Millimeter • Centimeter • Decimeter • Larger than a meter • Decameter • Hectometer • Kilometer**Standard English**Distance Volume/liquid Mass • 5280 ft = 1 mile • 3 ft. = 1 yd • 12 in = 1 ft • 1 gal = 4 qt • 1 qt = 2 pts • 1 pt = 16 oz • 1 lb = 16 oz Conversion 1 in = 2.54 cm 1 gal = 3.785 l 1 lb = 453.59 g 1 kg = 2.2 lbs**Prefixes of Metric Units**Prefix Example • Milli = 1/1000(thousandths) • Centi = 1/100 (hundredths) • Deci = 1/10 (tenths) • Meter (base) • Deca = tens • Hecto = hundreds • Kilo = thousands • 1 millimeter = 1/1000 meter • 3 centigrams = 3/100 gram • 6 deciliter = 6/10 liter • 7 meters = 7 meters • 2 decameters = 20 meters • 4 hectograms = 400 grams • 7 kilometers = 7000meters**Base**Gram (mass /weght) Meter (length) liter (volume/liquids)**1000**100 10 • Kilometer (km) = ______ meters • Hectometer (hm) = _______meters • Decameter (dam) = _______ meters • Meter = 1 meter • Decimeter (dm) = _____meter • _____dm = 1 meter • Centimeter (cm) = _______ meter • ______ cm = 1 meter • Millimeter (mm) = _______ meter • ______ mm = 1 meter 1/10 10 1/100 100 1/1000 1000**Meter**• Length • Slightly longer than a yard**Gram**• Mass (weight) • Kilogram is slightly more than 2 pounds**Liter**• Volume • Cubic meters (m3) • Dirt, sand and gravel • Liter • Liquids • Approximately the size of a quart**Where is industry mail headquarters located?**• Where are they located in MS? (address) • Do they have plants in other countries? If so list them • What do they produce? • List five careers for each industry. What will a person do in that career? • How do you apply for these jobs? Industry PACCAR American Eurocopter Stark Aerospace Nissan Toyota Severstal
