        BASIC UNITS OF MEASUREMENTS        METRIC UNITS OF LENGTH

        Linear......meter                       1 LIGHT YEAR = 9.46 X 10 KILOMETERS
        Volume......liter                       1 KILOMETER (km) = 1,000 METERS
        Weight......gram                        1 METER (m) = 100 CENTIMETERS
        International units..IU or U            1 METER (m) = 1,000 MILLIMETERS
                                   based on #/ml.           1 MICRON    = 1,000 MILLIMICRONS
        Whole Blood..1 unit = 500 mls.          1 MILLIMICRON = 10 ANGSTROMS (A)
        Equivalents...mEq (Elect. charge)

        METRIC UNITS OF WEIGHT             METRIC UNITS OF VOLUME

        1 metric ton = 1,000 kilograms          1 megaliter  = 1,000 kiloliters
        1 kilogram (kg) = 1,000 grams           1 kiloliter  = 1,000 liter
        1 gram (gm) = 1,000 milligrams          1 liter (l.) = 1,000 milliliters
        1 milligram (mg)= 1,000 micrograms      1 milliliter = 1,000 microliters

        GENERAL RELATIONSHIP BETWEEN UNITS

        1 gram of water = 1 milliliter = 1 cubic centimeter at 25°C

        TEMPERATURE                            PRESSURE

        C = 5/9 (F - 32)                       1 mm Hg = 1 Torr.
        F° = C° 9/5 + 32                       1 Atmosphere = 760 mm Hg.
        98.6°F = 37°C = 310°K                  1 Atmosphere = 14.696 lbs/sq in
        32°F = 0°C = 273°K                     1 mm Hg = 13.6 mm H20 = 1.36 cm H20
                                               1 BAR = 14.504 PSI at 0ft above Sea Level
