APPENDIX I
CONVERSION TABLES
This appendix gives the linear and liquid measure and weight equivalents of US units to metric units and vice versa. The metric system is a decimal system of weights and measures in which the gram (.0022046 pound), the meter (39.37 inches), and the liter (61.025 cubic inches) are the basic units of weight, length, and capacity respectively. Also included are conversion factors for the most commonly used measurements and weights. 
LINEAR MEASURE
Kilometers to miles (km x .621 = mi) (km ¸ 1.609 = mi) 1 = 0.62 2 = 1.24 3 = 1.86 4 = 2.48 5 = 3.10 6 = 3.72 7 = 4.34 8 = 4.96 9 = 5.58 10 = 6.21 20 = 12.42 30 = 18.63 40 = 24.84 50 = 31.05 
Miles to kilometers (mi x 1.609 = km) (mi ¸ .621 = km) 1 = 1.61 2 = 3.22 3 = 4.83 4 = 6.44 5 = 8.05 6 = 9.66 7 = 11.27 8 = 12.88 9 = 14.49 10 = 16.10 20 = 32.20 30 = 48.30 40 = 64.40 50 = 80.50 
LIQUID MEASURE
Gallons (US) x 3.785 = liters
Gallons (US) x 0.8327 = gallons (imperial)
Gallons (US) x 3.332 = quarts (imperial)
Quarts (US) x 0.946 = liters
Quarts (US) x 0.2082 = gallons (imperial)
Quarts (US) x 0.8327 = quarts (imperial)
Pints (US) x 0.473 = liters
Liters x 0.2642 = gallons (US)
Liters x 1.057 = quarts (US)
Liters x 0.2201 = gallons (imperial)
Liters x 0.8804 = quarts (imperial)
LIQUID MEASURE (continued)
Gallons (imperial) x 1.201 = gallons (US)
Gallons (imperial) x 4.802 = quarts (US)
Gallons (imperial) x 4.545 = liters
Quarts (imperial) x 0.3001 = gallons (US)
Quarts (imperial) x 1.201 = quarts (US)
Quarts (imperial) x 1.136 = liters
WEIGHTS
Short ton (US) = 0.91 metric ton
Long ton (US) = 1.02 metric tons
Pound (US) = 0.45 kilogram
SIMPLIFIED CONVERSION FACTORS FOR QUICK COMPUTATION
The following are accurate to within 2 percent:
 Inches to centimeters  Multiply by 10 and divide by 4.
 Yards to meters  Multiply by 9 and divide by 10.
 Miles to kilometers  Multiply by 8 and divide by 5.
 Gallons to liters  Multiply by 4 and subtract 1/5 of the number of gallons.
 Pounds to kilograms  Multiply by 5 and divide by 11.
