Ugh. Where did 660 feet come from? Where did 66 feet come from? A line of potatoes (linear) to measure an acre (area)? A strip of land 43,560 x 1 ft is an acre requiring 87k+ potatoes.
I'm no expert but i believe that's not how the term is used today. Like if a house is advertised as coming on a quarter acre of land, that says absolutely nothing about the dimensions of that land
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
You can divide 2400 square feet into an acre 18 times, but yeah... like, in most metros, even the kind of small detached single-family home you'd find in a inner-ring suburb is going to sit on a 5,000-8,000 square foot lot. Typical suburban lot sizes are more like a 1/4 acre.
This isn't to say that a McMansion on a quarter acre of land is a good thing, but just as a point of reference, if you're imagining a neighborhood of 15 to 20 homes and somebody tells you "that's about an acre" you're going to be off by an order of magnitude.
My 750sf circa-1960 starter home in a turn-of-century streetcar suburb sits on a 7,500sf lot, and that's relatively small for the area. You'd have to be talking about urban rowhouses as seen in East Coast cities to approach anything like a 2500sf lot size for a single family home.
18*2,400=43,200, so they’d fit, but not nicely. It also doesn’t take external wall width into account, but that’s 20 extra feet per house for the outside walls.
That said, at least in my area, most of the houses in that size range are two story, so who knows what the footprint would be. Agreed, unhelpful metric.
Meanwhile, Europeans use hectares. Or a hundred ares. An are is 100 square metres, so a hectare is 100*100 or 10000 square metres or 1/100 of a square kilometer.
