Weights and Measures
1 in = 2.540 cm 1cm = 10 mm = 0.3937 in
1 ft = 0.3048 m = 0.1667 fathoms 1m = 100 cm = 3.2808 ft = 0.5468 fathoms
1 fathom = 6 ft = 1.829 m 1000 m = 1 km = 0.6214 statute mi
1 L = 1.0567 U.S. qt
F° = (1.8 x C°) + 32C° = 5/9(F° - 32)
1 statute m = 5,280 ft = 1.609 km = 0.86899 nautical mi = 880 fathoms
1 nautical mi = 1.15078 statute mi = 1 min lat = 1.852 km = 1,012.6859 fathoms = 1,852 m
1 fathom = 0.0009875 nautical mi = 0.0011364 statute mi
1 lb = 0.4536 kg
total catch wt. in lbs ÷ 2.2046 = total catch wt. in kg
1 mt = 1,000 kg = 2204.6 lbs.
Area, Volume and Product Formulas
Number of Product Units x Average Unit Weight = Total Weight of Product
Area of a circle = πr 2 Circumference = 2πr (π = 3.1416)
Area of a square or rectangle = length × width
Area of a triangle = ½ X base X height
Volume of a right angle cone = 1/3 X πr 2 h
Volume of a Sphere = 4/3 X π X r 3
Length of the triangle hypotenuse “C” where A and B equal the length of the opposite two sides:
A 2 + B 2 = C 2 1/30/2004
