TABLES OF U.S. UNITS OF MEASUREMENT [Анг.] |
In these tables where foot or mile is underlined, it is survey foot or U.S. statute mile rather than international foot or mile that is meant.
Units of Length |
|
|
12 inches (in) |
= 1 foot (ft) |
3 feet |
= 1 yard (yd) |
16-1/2 feet |
= 1 rod (rd), pole, or perch |
40 rods |
= 1 furlong (fur) = 660 feet |
8 furlongs |
= 1 U.S. statute mile (mi) = 5280 feet |
1852 meters |
= 6076.115 49 feet (approximately) |
|
= 1 international nautical mile |
|
Units of Area |
|
|
144 square inches (in2) |

9 square feet |
= 1 square yard (yd2) |
|
= 1296 square inches |
272-1/4 square feet |
= 1 square rod (sq rd) |
160 square rods |
= 1 acre = 43 560 square feet |
640 acre |
= 1 square mile (mi2) |
1 mile square |
= 1 section of land |
6 miles square |
= 1 township |
|
= 36 sections = 36 square miles |
|

|
= 4 rods = 66 feet |
80 chains |
= 1 U.S. statute mile (mi) |
|
= 320 rods = 5280 feet |
|
Units of Liquid Volume |
|
|
4 gills (gi) |
= 1 pint (pt)= 28.875 cubic inches |
2 pints |
= 1 quart (qt) = 57.75 cubic inches |
4 quarts |
= 1 gallon (gal) = 231 cubic inches |
|
= 8 pints = 32 gills |
|
|
Units of Dry Volume |
|
|
2 pints (pt) |
= 1 quart (qt) = 67.200 6 cubic inches |
8 quarts |
= 1 peck (pk) = 537.605 cubic inches |
|
= 16 pints |
4 pecks |
= 1 bushel (bu) = 2150.42 cubic inches |
|

|
Avoirdupois Units of Mass |
|
[The "grain" is the same in avoirdupois, troy, and apothecaries units of mass.] |
|
27-11/32 grains |
= 1 dram (dr) |
16 drams |
= 1 ounce (oz) |
|
= 437-1/2 grains |
16 ounces |
= 1 pound (lb) |
|
= 256 drams |
|
= 7000 grains |
100 pounds |
= 1 hundredweight (cwt) |
20 hundredweights |
= 1 ton |
|
= 2000 pounds |
|
In "gross" or "long" measure, the following values are recognized: |
|
|
112 pounds |
= 1 gross or long hundredweight |
20 gross or long hundredweights |
= 1 gross or long ton |
|
= 2240 pounds |
|
Troy Units of Mass |
|
[The "grain" is the same in avoirdupois, troy, and apothecaries units of mass.] |
|
|
24 grains |
= 1 pennyweight (dwt) |
20 pennyweights |
= 1 ounce troy (oz t)= 480 grains |
12 ounces troy |
= 1 pound troy (lb t) |
|
= 240 pennyweights = 5760 grains |
