Conversion Factors (U.S. & Metric) ...

Linear Measure

Linear measure is used in determining distances and lengths, widths or thicknesses.

12 inches (in.) = 1 foot (ft.)
3 feet = 1 yard (yd.)
5 & 1/2 yards, or 16 & 1/2 feet = 1 rod (rd.)
40 rods = 1 furlong (fur.)
8 furlongs, or 320 rods = 1 mile (mi.)

Avoirdupois Weight

Avoirdupois weight is used in weighing heavy, course articles.

16 drams = 1 ounce (oz.)
16 ounces - 1 pound (lb.)
100 pounds = 1 hundredweight (cwt.)
20 hundredweights = 1 ton (T.)
2,000 pounds = 1 ton
2,240 pounds = 1 long, or gross, ton
7,000 grains (gr.) = 1 pound avoirdupois

Troy Weight

Troy weight is used in weighing precious minerals.

24 grains =1 pennyweight (pwt.)
20 pennyweights = 1 ounce
12 ounces = 1 pound
240 pennyweights = 1 pound
5,760 grains = 1 pound troy

Liquid Measure

Liquid measure is used in measuring the liquid capacity of containers. Also see "Cooking Measures" below.

4 gills (gi.) = 1 pint (pt.)
2 pints = 1 quart (qt.)
4 quarts = 1 gallon (gal.)
31 & 1/2 gallons = 1 barrel (bbl.)
63 gallons = 1 hogshead (hhd.)
2 barrels = 1 hogshead
7 & 1/2 gallons = 1 cubic foot

Dry Measure

Dry measure is used in measuring the volume of the contents of containers of solids. Also see "Cooking Measures" below.

2 pints = 1 quart (qt.)
8 quarts = 1 peck (pk.)
4 pecks = 1 bushel (bu.)
2 & 3/4 bushels = 1 barrel

Cooking Measures

Cooking measures are a combination of liquid and dry measurements ... rather obviously ... used in the kitchen & when cooking.

a pinch = 1/8 teaspoon or less
3 teaspoons (tsp.) = 1 tablespoon (Tbls.)
6 teaspoons = 2 tablespoons = 1 ounce
4 tablespoons - 1/4 cup (c.) = 2 ounces
8 tablespoons = 1/2 cup = 4 ounces
12 tablespoons = 3/4 cup = 6 ounces
16 tablespoons = 1 cup = 8 ounces
2 cups = 1 pint = 16 ounces (oz.)
4 cups = 1 quart = 32 ounces
4 quarts = 1 gallon (gal.) = 128 ounces
8 quarts =  2 gallons = 1 peck = 256 ounces
4 pecks = 1 bushel
16 ounces = 1 pound
