An acre is not just a unit of area measurement but has a traditional shape or aspect ratio per acre, based on the land plots it was used for.

1 acre is traditionally 60 ft x 660 ft, also known as 1 chain by 1 furlong.

It's similar to if you said you could lay X potatoes across a football field. Yes a football field is an area but it also has a defined length.

660 feet is a furlong, which comes from one furrow length. It’s the distance two oxen can pull a plow (creating a furrow), without stopping to rest. Then the oxen and person standing atop the plow could have a little rest before turning around to plow the next furrow. Not sure how many furrows but if you repeat this process all day, you’ll have plowed an acre. Potatoes did not exist to farmers when this land measurement was in use. But 66 x 660 is the original definition of an acre, and the only reasonable explanation for why we have 43,560

In California we measure water in Acre Feet. I guess if you know how many acres you have, and how many inches of water your crops need, I guess you’ll know how many acre feet you need.

It is a chain (66ft) and 10 chains 660ft. They are historically important units for land surveying (and relevant today because of that). The measurement is nonsense, but the graph makes sense because an acre can be defined as 1 chain by 10 chains or 66ftx660ft=4356sqft

These numbers all come from people who preferred 12 and 60 as their working base numbers, not 10. A lot of it becomes really elegant once you understand that.

What? You don't naturally measure things in potatoes per football field?

I just stole it from a place, sorry.

Homes here tend to be about that size unless they're older than about 1980. We also have a lot of absolutely massive mansions built out in the middle of absolutely nowhere that'll drive that number up quite a bit. If you're willing to drive 30 minutes to the grocery, you can get a 5000+sqft house for well under $500k. I have a buddy who just bought a 5200sqft place on 8 acres for about $450k. If you really want to live somewhere undesirable like the place my parents moved to a few years ago, their whole subdivision has a few dozen houses all over 7000sqft, and they sold for about $400k

0 here it is!

Yknow how hard it is to think in your second language? It's the same here. I know metric how metric works perfectly well, but I convert to imperial to think, and then convert the answer back to metric for whatever person needed it in metric. I literally have all the conversions memorized but I just can't think in metric. I say this because of the way you presented 10k square meters. Had to convert to miles to visualize and then was like "oh, a 16th of a mile squared"

Witch!

dict.cc lied to me!

That was a bad example, IKEA parking lots are different sizes. Sorry about that.

Sigh. 2.15 metres by 1.6 kilometers.

43,560 square feet = one acre.

The square root of 43,560 is 208.71 feet

208.71 feet/ 2.5 feet per step for men = 84 steps.

So walk 84 steps then turn a right angle and walk another 84. One acre is the area contained in that square.
