Conversion Formulas
BEGIN WITH	FORMULA for CONVERTING (Multiply Number of Units by Conversion Number to Obtain New Number of Units)
millimeters (mm)	millimeters x 0.03937 = inches
centimeters (cm)	centimeters x 10 = millimeters centimeters x 0.3937 = inches
meters (m)	meters x 1000 = millimeters meters x 100 = centimeters meters x 3.281 = feet meters per second x 3.281 = feet per second square meters x 10.76 = square feet square meters x 1.196 = square yards square meters x 0.0002471 = square acres cubic meters x 35.31 = cubic feet cubic meters x 1.308 = cubic yards cubic meters x 0.0008107 = acre-feet cubic meters per second x 35.31 = cubic feet per second cubic meters per second x 15,850.00 = gallons per minute
kilometers (km)	kilometers x 1000 = meters kilometers x 0.6214 = miles square kilometers x 0.3861 = square miles cubic kilometers x 0.2399 = cubic miles
inches (in)	inches x 25.4 = millimeters inches x 2.54 = centimeters square inch x 6.4516 = square centimeters
feet (ft)	feet x 12 = inches feet x 0.3048 = meters square feet x 0.09294 = square meters cubic feet x 0.02832 = cubic meters acre-foot x 1233 = cubic meters
yard (yd)	yard x 3 = feet yard x 0.9144 = meters
miles (mi)	miles x 5280 = feet miles x 1609.3 = meters miles x 1.609 = kilometers square miles x 2.590 = square kilometers cubic miles x 4.168 = cubic kilometers
acre-foot (acre-ft)	acre-ft x 1233 = cubic meters
microradian	microradian x 0.2 = second of arc
Temperature Conversions
degrees Fahrenheit (F) degrees Celsius (C)	(F - 32) x 5/9 = C (C x 1.8) + 32 = F
	(C x 2) - (C x 2 x 0.1) + 32 = F   a) double the Celsius temperature b) subtract 10% of the doubled temperature c) add 32
Weights and Measures (Left Column Equals Right Column)
1 cup	= 8 fluid ounces = 4.8 ounces = 137 grams dry weight
	= 8 ounces = 16 tablespoons = 48 teaspoons
1 gallon	= 0.1337 cubic feet = 231 cubic inches = 3.785 liters = 8.336 pounds of water = 133.376 ounces of water
1 liter	= 0.001 cubic meter = 1.057 quarts = 0.2642 gallons = 0.03531 cubic feet
1 ounce	= 0.0625 pounds = 28.35 grams = 437.5 grains
1 pound (Avoirdupois)	= 16 ounces = 0.4536 kilograms = 7000 grains = 1.2153 pounds Troy
1 quart	= 2 pints = 0.25 gallons = 0.9464 liters = 2.084 pounds of water
