1. Metric System Unit 2

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

3. 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

4. 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

5. 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

6. Base Gram (mass /weght) Meter (length) liter (volume/liquids)

7. 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

8. Meter • Length • Slightly longer than a yard

9. Gram • Mass (weight) • Kilogram is slightly more than 2 pounds

10. Liter • Volume • Cubic meters (m3) • Dirt, sand and gravel • Liter • Liquids • Approximately the size of a quart

11. Complete exercise 2-1

12. 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?
