Where can I find a list of common conversions?

LIQUIDS

 1 Tbsp = 3 tsp
 1 fl. oz. = 6 tsp = 2 Tbsp = 29.573 mL
 1 pint = 16 fl. oz. = 2 cups = 473.17 mL = 0.473 L
 1 quart = 2 pints = 32 fl. oz. = 946.34 mL
 1 gal = 4 quarts = 8 pints = 128 fl. oz. = 3.785 L
 6 fl. oz. = 3/4 cup
 8 fl. oz. = 1 cup

HELPFUL TIPS

 1½ Tbsp in 3 gal of water = 1½ tsp in 1 gal of water 
 2 Tbsp in 3 gal of water = 2 tsp in 1 gal of water

 AREA
 1 sq ft = 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
 0 C Freezing point of water = 32 F
 10 C Warm winter day = 50 F
 20 C Mild spring day = 68 F
 30 C Hot summer day = 86 F
 37 C Normal body temperature = 98.6 F
 40 C Heat wave conditions = 104 F
 100 C Boiling point of water = 212 F
