Re: [MacGroup] metric and fractions

Marta: Read back. The old circle has 360 degrees, So the earth is divided into 360 slices of mellon, and it takes the earth one whole day to make the circle, so it takes 24 hours, which means that ever hour the celestial noon moves 360/24= 15 degrees. Since one degree is 60 nautical mile

Lee: Lee, you are certainly correct, but I can see you have never done any surveying. No survey that I ever heard about had a boundary using yards. If you check the Kentucky Department of State, you will find that the first 30,000 surveys made in Kentucky used the measurement of poles and

Very interesting. Where is Marquette County? How about getting Jefferson County to convert all their surveys to feet. Neal PS: Didn't you ever run into any 3:4:5 triangles? On Jan 46, 1120092007, at 8:35 AM, Lee Larson wrote: On Jan 5, at 4:06 PM, Neal Hammon wrote: > Lee, you are certainly co

Hi all, My favorite acre computation is to figure out the amount of runoff from a rainstorm. Converting inch-acres to gallons without paper and pencil is a good way to make a long drive short. Bill ___ The next Louisville Computer Society meeting w

Robert: On one of my first days in the office, I was working on concrete beam designs using my slide rule, when an old senior engineer walked by, stopped to look at my results, and then gave me some advice. "Too many decimal places. " he said, " Just remember that engineering is an exact sci

Re: [MacGroup] metric and fractions

Bill: I worked it out another way: One cubic feet of water = 7.48052 gallons of water One cubic feet of water, when one inch deep, covers 12 square feet. One acre covers 43,560 square feet. Thus 12/7.48052 = 43,560/x ... So, x = 27,154.287 That's how I came up with an answer, right or wrong.
