The chain is 30cm length and you have 15 lengths. Therefore 30/15 is 2cm length for each link. 2cm is 20mm.
I would like to secure my fence. What are the best options for a chain link to be used on the fence?
because if it kept going on they would all eat each other
103 centimetres are equal to 1030 millimetres.
Yes. One centimetre is 10 millimetres, thus, 3 centimetres would be 30 millimetres, whereas 20 millimetres would be 2 centimetres.
because energy has to travel up the food chain, and by the 9th link there is very little energy for the animal to use
Most chains have links so I would say that each step is called a link.
The topmost link would break, as it needs to hold the weight of the weight itself plus all the chain links below it. Thus this topmost link reaches the 1000-pound limit before all the others.
This would depend on what sprockets you are running and what chain you plan to run. If you don't have a local shop to ask, I would go to this website and ask them: http://www.1trail.com/sa/p/Driven_USA_Suzuki_DZR_400_00-_04_MX_Front_Sprocket.htm
If I was you i would use millimetres or centimetres.
There are 1000 millimetres in 1 metre so there would be 35000 millimetres in 35 metres.
the one below it will die because it will have nothing to keep its population down and then it will eat up all its food so it and its food dies and then humans will because the world has ran out of food.
Millimetres
