Baseball fields have too many different dimensions and curves in the
outfield to get a visual size perception of the area.
Baseball fields are non standard in the outfield while all American
football fields have uniform standard dimensions (100 yards long plus 10 yard
end zones). 110 yards is very close to 100 m.
If you want to use baseball fields, then use the baseball diamond where the
bases provide the square standard 90 feet on a side (between bases). What's
that in metric area dimension?
A baseball diamond area may be more appropriate for use in estimating
smaller size areas like home lots.

May I suggest a baseball field - a large field is larger than a hectare, a
small one is less than a hectare. Try plotting a quarter circle radius 112
metres onto the batters plate

Hi Pat et al,
The hectare is a great, useful and easy to visualize SI unit since it's
100 x 100 m.
In American terms, 100 m is the length of a football field plus one end
zone.
What is better to visualize an area?

Dear All,
I am quoting from a web page defined as a 'rant'. It says in part:
An example from land measurement shows how akward the imperial measurements
can be.
What is an acre? At one time it was defined as the amount of land one man
and a team of oxen could plow in one day. The acre was later standardized to
660 feet by 66 feet or 43,560 square feet. There are 640 acres in a square
mile. A square mile is 5,280 feet by 5,280 feet or 27,878,400 square feet.
Contrast the above with the metric hectare. A hectare is 100 meters by 100
meters or 10,000 square meters. There are 100 hectares in a square kilometer. A
square kilometer is 1,000 meters by 1,000 meters or 1,000,000 square meters.
Now which looks simpler? Which would be easier to recall or teach?
