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 5280 ft = 1 mile 3 ft. = 1 yd 12 in = 1 ft Volume/liquid 1 gal = 4 qt 1 qt = 2 pts 1 pt = 16 oz Mass 1 lb = 16 oz

5. Prefixes of Metric Units PrefixExample 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 = 7000 meters

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

7. 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 1000 100 10 1000 100 10 1/10 1/100 1/1000
