THE METRIC SYSTEM AND EQUIVALENTS
LINEAR MEASURE
SQUARE MEASURE
1 Centimeter = 10 Millimeters = 0.01 Meters = 0.3937 Inches
1 Sq. Centimeter = 100 Sq. Millimeters = 0.155 Sq. Inches
1 Meter = 100 Centimeters = 1000 Millimeters = 39.37 Inches
1 Sq. Meter = 10,000 Sq. Centimeters = 10.76 Sq. Feet
1 Kilometer = 1000 Meters = 0.621 Miles
1 Sq. Kilometer = 1,000 Sq. Meters = 0.386 Sq. Miles
WEIGHTS
CUBIC MEASURE
1 Gram = 0.001 Kilograms = 1000 Milligrams = 0.035 Ounces
1 Cu. Centimeter = 1000 Cu. Millimeters = 0.06 Cu. Inches
1 Kilogram = 1000 Grams = 2.2 Lb.
1 Cu. Meter = 1,000,000 Cu. Centimeters = 35.31 Cu. Feet
1 Metric Ton = 1000 Kilograms = 1 Megagram = 1.1 Short Tons
