1 pound = 16 ounces = 454 grams

1 ounce = 28.35 grams

1 kilogram = 2.2 pounds

1 cubic foot = 62.4 pounds = 7.5 gallons of water = 0.03 cubic meters

1 acre-foot of water = 2,718,000 pounds = 326,000 gallons = 43,560 cubic feet

1 gallon of water = 8.34 pounds = 3,800 cubic centimeters = 3,800 grams = 3.785 liters

1 liter of water = 0.264 gallons

1 part per million (ppm) requires:

  • 2.7 pounds per acre-foot
  • 0.0038 grams per gallon
  • 0.0283 grams per cubic foot

0.6 mile = 1 kilometer

1 inch = 25 millimeters = 2.54 centimeters

To figure formulation for treating ponds with herbicides:

  • 1 % solution
    • = 1.34 ounces/gallon
    • = 38 grams/gallon
    • = 10 grams/liter

1 gallon = 4 quarts = 8 pints

1 pint = 16 ounces

1 cup = 8 ounces

1 tablespoon = ½ ounce

1 acre = a square with 209 feet per side

1 acre = a circle with a diameter of 235 feet

1 hectare = 2.471 acres = 107.640 square feet = 10,000 square meters

Degrees Centigrade = (degrees Fahrenheit - 32) x 5/9

Degrees Fahrenheit = 9/5 x degrees Centigrade + 32
