Information That is Handy to Have

For most folks involved in agriculture, and even some who only maintain their landscapes, there is always a lot of information you have to know or at least have it handy to refer back to. Trying to remember it all is difficult if not impossible. Listed below is some information, (facts/figures) that is included in a little publication, called a Reference Guide for Texas Ranchers which can be found posted on the Brown County Extension website, brown.agrilife.org.

Area:

• 1 acre = 43,560 square feet, 209 feet x 209 feet, 69.5 yards x 69.5 yards
• 1/10 acre = 4,356 square feet, 66 feet x 66 feet, 22 yards x 22 yards
• 1/100 acre = 436 square feet, 21 feet x 21 feet, 7 yards x 7 yards
• 1 section = 640 acres or 1 square mile
• 1 hectare = 2.471 acres

Length:

• 1 mile = 5,280 feet, 1,760 yards or 1.61 kilometers
• 1 rod = 16.5 feet
• 1 chain = 66 feet
• 1 kilometer = 0.62 miles
• 1 roll of barbed wire = 1/4 mile or 1,320 feet
• 1 roll of net wire = 330 feet or 20 rods

Weight:

• 1 short ton = 2,000 pounds
• 1 long ton = 2,240 pounds
• 1 pound = 453.6 grams or 16 ounces
• 1 kilogram = 2.2 pounds

Liquid Measure:

• 1 gallon = 128 ounces, 3,785.4 milliliters, 16 cups, 4 quarts, 8.355 pounds or 256 tablespoons
• 1 quart = 0.946 liters, 2 pints or 32 ounces
• 1 pint = 16 ounces or 2 cups
• 1 cup = 8 ounces
• 1 milliliter = 1 cubic centimeter (cc)
• 1 tablespoon = 3 teaspoons
• 1 teaspoon = 5 milliliters
• 1 cubic foot of water = 62.43 pounds or 7.48 gallons

• 1 acre inch of water = 27,154 gallons
• 1 barrel of water = 55 gallons
• 1 barrel of oil = 40 gallons

Calculation of Water Storage Capacity:

• Round tank (gallons) = 3.1416 x radius squared (ft.) x height (ft.) x 7.48
• Rectangular tank (gallons) = height (ft.) x width (ft.) x length (ft.) x 7.48

Pressure:

• 1 foot lift of water = 0.433 psi
• 1 psi will lift water 2.31 feet
