LIQUIDS
1 tablespoon = 3 teaspoons
1 fl. oz. = 6 teaspoons = 2 tablespoons = 29.573 milliliters (mL)
1 pint = 16 fl. oz. = 2 cups = 473.17 mL = 0.473 liters (L)
1 quart = 2 pints = 32 fl. oz. = 946.34 mL
1 gallon = 4 quarts = 8 pints = 128 fl. oz. = 3.785 L
6 fl. oz. = 3/4 cup
8 fl. oz. = 1 cup
HELPFUL TIPS:
1-1/2 tablespoons in 3 gallons of water = 1-1/2 teaspoons in 1 gallon of water
2 tablespoons in 3 gallons of water = 2 teaspoons in 1 gallon of water
AREA
1 square foot = 929.030 square centimeters (sq. cm.)
1 acre = 43,560 sq. ft. = 4,046.856 square meters
WEIGHT
1 oz. = 28.35 grams
DETERMINING SQUARE FEET
RECTANGLE: Length x width
TRIANGLE: The height (or length) x half of the base (or width)
CIRCLE: The diameter squared x 0.7854 (Diameter is the length of a straight line through the center of the circle.)
DETERMINING CUBIC FEET
Length of room x width of room x height of room
TEMPERATURE
Celsius: Multiple by 1.8 (=9/5), +32 = Fahrenheit
Fahrenheit: -32, multiple remainder by .5556 (=5/9) = Celsius
