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
