3. Why Go Metric? • Distance 1 foot = 1 yard = 1 mile = 12 inches 3 feet 5,280 feet = 36 inches = 1,760yards = 63,360 inches!

4. Why Go Metric? 1/7,000 pound 16 ounces 1 short ton 2,240 pounds • Weight 1 grain = • 1 pound = 2,000 pounds = • 1 long ton =

5. Why Go Metric? • Volume 3 teaspoons = 1 tablespoon 2 tablespoons = 1 fluid ounce 3 tablespoons = 1 jigger 1 cup = 8 fluid ounces 2 cups = 1 pint 2 pints = 1 quart 4 quarts = 1 gallon

6. Base Units • Meter (m) • Gram (g) • Liter (L) • Distance – • Mass – • Liquid Volume –

7. Nature, not Artifice • The meter is defined as the distance that light travels in 1/299,792,458 of a second • Speed of light is 299,792,458 meters per second • Liter is the volume of a 10 centimeter cube (1,000cm3) • The kilogram is based on the mass of 1 liter of water.

8. Prefix • Each prefix denotes a multiple of the base unit • Deca (da) :10 (ten) • Hecto (h):100 (hundred) • Kilo (k): 1,000(thousand) • Mega (M): 1,000,000(million) • Giga (G): 1,000,000,000(billion) • Tera (T): 1,000,000,000,000(trillion)

9. Prefix • Each prefix denotes a multiple of the base unit • Decameter: 1dam = 10m • Hectometer: 1hm = 100m • Kilometer: 1km = 1,000m • Megameter: 1Mm = 1,000,000m • Gigameter: 1Gm = 1,000,000,000m • Terameter: 1Tm = 1,000,000,000,000m

10. Prefix • Each prefix denotes a fraction of the base unit • Deci (d): 0.1(tenth) • Centi (c): 0.01(hundredth) • Milli (m): 0.001(thousandth) • Micro (µ): 0.000001(millionth)

11. Prefix • Each prefix denotes a fraction of the base unit • Deciliter: 1dL = 0.1L • Centiliter: 1cL = 0.01L • Milliliter: 1mL = 0.001L • Microliter: 1µL = 0.000001L
