#### (Common Formulas and Conversion Tables)

1 inch = 2.54 centimeters (cm)
1 foot = .304 meters (m)
1 mile = 1.6093 kilometers (km)
5,280 feet = 1 US mile
1 km = .6124 US miles
1 sq. mile = 2.59 sq. km

1 nautical mile = 1.852 km
1 fathom = 1.8288 mtr
6 feet = 1 fathom
120 fathoms = 1 cable length
6,076.11 feet = 1 nautical mile

1 ounce = 28.35 grams
1 pound = .4536 kilograms
1 short ton = .9078 metric ton
1 short ton = 2000 pounds
1 long ton = 1.016 metric tons
1 long ton = 2240 pounds
1 metric ton = 1000 kilograms

1 quart = .94635 liters
1 US gallon = 3.7854 liters
1 Imperial gallon = 4.5459 liters

32 degrees Fahrenheit (f) = 0 degrees Celsius (c)
0o f = -18o c
1o f = 5/9o c
100o c = 212o f
100o f = 38o c

To convert f to c :
Subtract 32, Multiply by 5, Divide by 9
i.e. 98of -32 = 66 x 5 = 330 / 9 = 36.66667oc

To convert c to f :
Multiply by 9, Divide by 5, Add 32
i.e. 22oc x 9 = 198 / 5 = 39.6 + 32 = 71.6of

Freezing point of Water (fresh) = 32of or 0oc
Boiling point of Water (fresh) = 212of or 100oc

### Speed, Time and Distance

Time = 60 x Distance / Speed
Speed = 60 x Distance / Time
Distance = Speed x Time / 60

Hull speed = Square Root ( Length of Water Line) x 1.3

<

Note: The hull or boat speed is the maximum calculated speed the hull will travel through the water. This is, of course as all sail boat racers will tell you, not even close to what their boat will do. This is the designers mathematical or theoretical maximum boat speed.
