GENERAL INFORMATION

● The inside length (grip or pitch) of one link is 4 wire diameters.
● The outside length of one link is 6 wire diameters.
● The outside width of one link is 3.56 wire diameters.
● The gauge-test length is the outside length over 6 links and equals 26 wire diameters.
● The weight of one links is about 3-1/3 times its wire diameter cubed.
● Doubling the wire diameter of one link multiplies its weight by 8.
● The weight of 1 linear foot of chain is 10 times its wire diameter squared.
● The length of a standard "shot" = 15 fathoms = 90ft.= 1080".
● The weight of a 90ft. shot = 900 times its wire diameter squared.
● Doubling the wire diameter of a 90ft. shot multiplies its weight by 4.
● Doubling the size of chain theoretically multiplies its strength by 4, in practice, by a trifle  less than 4.
● The safe working load of chain is ordinarily assumed as one half the proof test.

CONVERSION

1 lbs = 0.454 kg. 1 cwt = 50.8 kg.
1 ton (long) = 1016 kg.   1 KN = 98 kg.
1 N = 0.98 kg. 1 inch = 25.4 mm
1 foot = 304.8 mm 1 fathom = 1.828 m
