Arc 1º = 0.01745 radian
Base of Natural Logs = 2.718
1 cubic foot of water at 4º C (weight) = 62.43 lb
1 foot of water at 4º C (pressure) = 0.4335 lb/in2
Velocity of light in a vacuum, c = 186,280 mi/sec = 2.998 x 1010 cm/sec
Velocity of sound in dry air at 20º C, 76 cm Hg = 1127 ft/sec

Acceleration due to gravity at sea level, 40º Latitude, g = 32.1578 ft/sec2
1 inch of mercury at 4º C = 1.132 ft water = 0.4908 lb/in2

 

Linear Measure
12 inches = 1 foot
3 feet = 1 yard = 36 inches
5 ½ yards = 1 rod or pole – 16 ½ feet
40 rods = 1 furlong = 220 yards = 660 feet = 1/8 mile
8 furlongs = 1 statute mile = 1760 yards = 5280 feet
3 miles = 1 league = 5280 yards = 15840 feet
Side of a square = 0.707 * (diagonal of the square)
Diagonal of the square = 1.414 * (length of side)
Diagonal of the rectangle = √(length2 + width2)

Square Measure
144 square inches = 1 square foot
9 square feet = 1 square yard
30 ¼ square yards = 1 square rod = 272 ¼ square feet
160 square rods = 1 acre = 4840 square yards
640 acres = 1 square mile = 3,097,600 square yards

Circular Measure
60 seconds = 1 minute (‘)
60 minutes = 1 degree (“)
90 degrees = 1 quadrant
4 quadrants = 1 circumference
Circumference = 2 * PI * radius = PI * diameter
Area of a circle = PI * radius2
Arc Length = PI * radius /180 * angle

Cubic Measure
1728 cubic inches = 1 cubic foot
27 cubic feet – 1 cubic yard
144 cubic inches = 1 board foot
128 cubic feet = 1 cord

Liquid Measure
4 gills = 1 pint
2 pints = 1 quart = 8 gills
4 quarts = 1 gallon = 8 pints = 32 gills
31 ½ gallons = 1 barrel = 126 quarts
2 barrels = 1 hogshead = 63 gallons = 252 quarts

Dry Measure
2 pints = 1 quart
8 quarts = 1 peck = 16 pints
4 pecks = 1 bushel = 32 quarts = 64 pints
105 quarts = 1 barrel (for fruits, vegetables, and other dry commodities) = 7056 cubic inches

Nautical Measure
6 feet = 1 fathom
100 fathoms = 1 cable’s length (ordinary) = 608 feet (Br.) = 607.61 feet (US)
120 fathoms = 1 cable’s length (U S Navy)
10 cable’s length = 1 nautical mile = 6080 feet (Br.) = 6076.1033 feet (US)
1 nautical mile = 1,1508 statute miles
3 nautical miles = 1 league (marine)
60 nautical miles = 1 degree (of a terrestrial great circle)

Avoirdupois Weight
27 11/32 grains = 1 dram
16 drams = 1 ounce = 437 ½ grains
16 ounces = 1 pound = 256 drams = 7000 grains
100 pounds = 1 hundredweight = 1600 ounces
20 hundredweight = 1 ton = 2000 pounds
112 pounds = 1 long hundredweight
20 long hundredweight = 1 long ton = 2240 pounds

Troy Weight
24 grains = 1 pennyweight
20 pennyweights = 1 ounce = 480 grains
12 ounces = 1 pound = 240 pennyweights = 5760 grains

Apothecaries’ Weight
20 grains = 1 scruple
3 scruples = 1 dram = 60 grains
8 dram = 1 ounce = 23 scruples = 480 grains
12 ounces = 1 pound = 96 drams = 288 scruples = 5760 grains

The chief symbols are I = 1; V = 5; X = 10; L = 50; c = 100; D = 500; M = 1000. Note that IV = 4, means 1 short of 5; IX = 9, means 1 short of 10; XL = 40, means 10 short of 50; and XC = 90 means 10 short of 100, Any symbol following one of equal or greater value adds its value – II = 2. Any symbol preceding one of greater value subtracts its value – IV = 4. When a symbol stands between two of greater value its value is subtracted from the second and the remainder added to the first – XIV = 14; LIX = 59. Of two equivalent ways of representing a number, that in which the symbol of larger denomination preceded is preferred – XIV instead of VIX for 14.
