Ok, Some math I am great at , some, kinda outa practice. I cant find my convertion tables. Anyway, I have a small goofy shaped feild I need to know the acreage of today. I do not have a measuring wheel, but with the ATV trip meter I come up with a feild perimitor of 6.5 tenths of a mile, small feild I know. As best I can figure , it is just under 5 acres, can any one give me a more educated acreage? I have 3 other feilds I need to know the acreage on , but I have some time for that. Thank you in advance, well , off to pick them 12,000 eggs, still no calves, sure hope that close one waits till the next two days pass by.

43,560 square feet in an acre. A square or rectangular field, you take the Length X the Width to get square feet, then divide by 43,560.

Most farm supply stores sell measuring wheels. Some measure in Feet, some in "Wheels". One that measures in wheels is 6.6 feet around. This is a function of the square root of 43,560. Those that measure in wheels, you can multiply Wheels X Wheels, the move the decimal three places to the right and you have acres automatically, with no conversion. Odd shaped field, you break up into squares, right triangles or rectangle and use some Kentucky windage. The old surveyers "chain" was 66 feet long, but you had to drag it behind you.

The Garmin, Etrex ledgend GPS has an acreage measurement function under the accessories section. They are moderately accurate, run around $150.

Your county FSA office will also provide you with an aerial photograph with the acres shown for each field, as long as boundaries have not changed.

Dave if you have a handheld gps unit it will probably do an area calculation. On one of the menus there is likely a choice for calculate area, then just drive the edge of the field.

Here is a software program anyone can use and it's free. It runs based on google maps. You just zoom to the overhead view of your farm and place the points around the perimeter of your fields. I have crossed checked it with FSA numbers and surveyed platts and it is pretty daggum accurate.

More information is needed. If it is a perfect circle, you would have 21 acres, perfect square is 16.6 acres, a plot 250'x1453' would be 8 acres...

What does it look like?

A perfectly square field would have sides of 858 ft for a total circumference of .65 miles. If you multiply 858 x 858 and divide by 43560 (number of square feet in an acre), you end up with about 16.9 acres. Even if the field is rectangle with equal sides and ends the area should be about the same. Of course an odd shaped field that curves in and around will really throw that off. Good luck

If is is a irregular shape try to divide it into 90 degree right angles. Muliply the length by the width and for right angles divide by 2. That will give you the square feet. Divide that answer by 43260 and you will have the acres. Add all of the right angles of acres together and you will have your total acres.

Hi Dave,

16.9a

5280x.65=3432ft/4=858x858=736164sft/43560=16.9a

I have never been taught how to figure out acreage,always been told how many acres in the field or went by the meters on the planters,but anyone that can figure it out by the four measurements should be able to figure it out by multiplying your stared measurement by 5280 and than dividing by 4,giving you four equeal sides in yards?

You cannot get a meaningful figure unless the field is square or circular. It could be only a metre wide. Just need a little more info than just the perimeter.

Sorry, just knowing the around is not enough. So like if it were a perfect circle it would have the most. If it were 1 foot wide and 3+ milels long, it would have very little.

C'mon, the perimeter would be about6 miles and 2 ft.

If it was a rectangle shape it would not matter how wide or long it was. The area would be the same whether it was long and narrow or a perfect square.

Seems like that would be true, but its not. A plot 10' x 990'= .23 acres, while a plot 400' x 600'= 5.51 acres. Both have a perimeter measurment of 2000 feet. The closer you get to square, the more the area. 500' x 500' is 5.74 acres. 1' x 999' = .02 acre.

Sorry, I read that as 6 miles and 5 tenth around. Around here, 6 tenth of a mile around isn't a field, it a "patch" or that "corner" . Actually, we could assume a circle and figure from that and that would give him the very maximum that it could be. Margin of error with ATV is very big.

I agree, the maps they send Dad always have the correct acreage on them... it even matches what we come up with on the air seeder monitor.

They can pull up that satallite view on the computer and have ya an answer before you can find a pencil and paper.

Really slick how that software can measure.

I pulled some sod out of buffalo grass and they measured it within seconds. Took a year to get the okay to farm the ground tho.

Wheat was 6" tall before they said it was okay for me to plow it up. :>)

Hold the phone!

Now you gotta get permission from the gumment to plow up ground and farm it? "I don't need no stinkin' permission!" What's the deal?

Can you get leagal charges brought against you or do they just cut off your agriwellfair check? I know alot of frogponds get drained and goat ground gets turned around here because the land owner does not take any USDA funds.

Yes, sir! You don't break up any new ground unless you get Unc's permission and if it isn't farmable they won't let you do anything. BTDT
BUT, sometimes if you know the right people and have the money you can do anything, leagal or not.
