32 points of a compass = 360 degrees
1 point of a compass = 11.25 degrees
To convert degrees C. to degrees F., multiply by 9, divide by 5 and add 32
To convert degrees F. to degrees C., deduct 32, multiply by 5 and divide by 9
1 inch = 2.54 centimeters
1 foot (U.S.) = .3048 meters = 1 British foot
1 kilometer = 3,280.8399 feet = .5399568 nm
Statute mile = 5,280 ft = 1.609 km = .869 nm
Nautical mile = 1.15 stat miles = 1,852 m = 6,076.12 ft = about 2,000 yds (1 minute of latitude)
Length of 1 minute of latitude at equator = approximately 6,046 ft
Length of 1 minute of latitude at poles = approximately 6,108 ft
Knot = 1 nm/hr = 1.15 mph = 1.852 km/hr
Fathom = 6 ft = 1.829 m
Cable = 720 feet = 120 fathoms
Cable (British) = .1 nm
7.5 cables = 1 statute mile
8.44 cables = 1 nm
Charts - nautical miles per inch = reciprocal of natural scale/72,913.39
Charts - statute miles per inch = reciprocal of natural scale/63,360
Charts - inches per nm = 72,913.39 x natural scale
Charts - inches per sm = 63,360 x natural scale
Charts - natural scale = 1:72,913.39 x nm/inch
Charts - natural scale = 1:63,360 x sm/inch
Std. atmospheric pressure at sea level = 29.92126 inches of mercury
millibar = .02952998 inches of mercury
millimeter of mercury = 1.3332237 millibars
register ton = 100 cubic feet
measurement ton = 40 cubic feet = 1 freight ton
1 barrel (42 gals) of diesel fuel = 315 pounds
1 gallon of engine motor oil = 7.3 pounds
1 cubic foot = 7.481 gals of water
cubic foot of seawater = 64 lbs
cubic foot of freshwater = 62.428 lbs @39.2 degrees F. (temp. of max. density)
1 cubic foot of normal storage ice = 62 lbs
Speed of sound is approximately 1,117 feet per second
Approximate distance (nm) of a flash of light to resulting sound = elapsed time divided by 5.5
1 displacement ton = 35 cubic feet of seawater = 1 long ton
1 ton of freshwater=35.84 cubic feet
