How much does sea water weigh per cubic kilometer?
I once had a book about the ocean that claimed that there was 38 pounds of gold in one cubic mile of seawater. You could figure 1 cubic kilometer from here but you are still left with the validity of the claim of the book and even worse, my memory of that book. Still, something to play with.
Which is greater a nautical mile or a mile?
A nautical mile (NM) is the distance, of one minute (60 minutes = one degree) of latitude along the Prime Meridian passing through Greenwich, England. Ships at sea used sextants and the stars to determine latitude, so it was easy to measure distance using a unit based on latitude.The statute mile is so named because it was standardized by an act of Parliament in 1593, i.e., a statute. It is also called a surveyors mile, or more commonly, mile. The mile is based on the old Roman unit of distance, the mil (meaning thousand) that was equal to one thousand paces (two steps). Stones were placed every mil along roads to indicate the distance to Rome, thus the term milestones, and the saying "All roads lead to Rome."1 Nautical mile = 1.15 statute miles
