1 pound water = 27.7 cubic inches = 0.1198 gallons | Area = Square of Diameter x .7854 or |
1 cubic foot water = 62.43 pounds | Radius x 3.1416 |
1 gallon water = 8.345 pounds | |
Circumference = Diameter x 3.1416 | |
Length | |
1 inch = 2.54 centimeters | Diameter = Circumference ÷ 3.1416 |
1 centimeter = 0.39 inches | |
1 foot = .0305 meter | Area of Circular Ring = .7854 x (Outside Diameter Squared minus Inside Diameter Squared) |
1 meter = 3.28 feet | |
1 mile = 1.61 kilometers | Doubling diameter increases area four (4) times |
1 kilometer = .62 miles | Tripling diameter increases area nine (9) times |
Inches to centimeters - multiply by 2.54 | Square/Rectangle |
Centimeters to inches - multiply by .039 | Area = Length x Width |
Feet to meters - multiply by 0.305 | Diagonal = Square Root of width squared + length squared |
Meters to feet - multiply by 3.28 | |
Volume | Side (square only) = Diagonal x .7071 |
1 fluid ounce = 29.57 milliliters | |
10 milliliters = 0.34 fluid oz | Triangle |
1 quart = 9.46.35 milliliters | Area = Base x 1/2 of perpendicular height |
1 liter = 1.06 US quarts | |
1 gallon = 3.79 | Cube |
Area of surface = Square of side x 6 | |
Ounces to milliliters - multiply by 29.57 | |
Milliliters to ounces - multiply by 0.034 | Volume = Cube of side |
Quarts to liters - multiply by .095 | Diagonal = Side x 1.732 |
Liters to quarts - multiply by 1.06 | |
Cylinder | |
1 cubic inch = 16.39 cubic centimeters | Area of Curved Surface = Diameter x Length x 3.1416 |
1 cubic foot = 1728 cubic inches = 7.48 gallons | |
1 cubic yard = 27 cubic feet = 0.7646 cubic meters | |
Volume = Square of Diameter x .7854 x length | |
Cone | |
Area of Curved Surface = Diameter of Base x Slant Height x 1.5708 | |
Volume = Diameter of Base Squared x Perpendicular Height x .2618 or Area of Base x 1/3 Perpendicular Height |
