Because a nautical mile is equal to one minute in lat/lon. And 60 minutes = 1 degree in lat/lon.
So a nautical mile is also 1/60 of a degree.
In lumberjack competitions there is an event called Chain Throw that still uses the chain. This was never my event when competing, but it definately is a specialized skill.
The measurment is still used in timber cruising and forestry in general.
The chain, at 66 feet, is how wide a street is. Measure 33 feet from centre of the street, and that’s the municipality’s property, not yours. Even if it intrudes onto what you think as your property, it belongs to the municipality.
I’ll play Australian horse racing, when I can. It’s usually on too late for me. But on the rare occasions when I can, it’s always in metric, which our North American broadcaster tries to translate into Imperial. Thus, 1600m becomes a mile, 1200m becomes five furlongs, and so on. Basically, 200m (220 yards) is a furlong, which should be done by a racehorse in 12 seconds. Knowing that time measurement is how I’ve succeeded at Australian racetracks, even though they’re in metric.
Regardless, horse racing anywhere is a pleasant hobby. Keep the wagers small, and enjoy!
A Nautical mile is equal to one minute of latitude but generally not one minute of longitude.
The length of one minute of longitude depends on your latitude. At the equator one nautical mile is 1.0016 nautical miles (because the earth is slightly ellipsoid) at my latitude (in Scotland) one minute of longitude is about 0.55 nautical miles. Only at a latitude of +/- 3.239 degrees is one degree of longitude equal to one nautical mile.
This varies greatly among municipalities. Sometimes the lot extends to the center line of the street, sometimes to the “service” line where the water and sewer hookups are, sometimes to the edge of the street, sometimes to the edge of the sidewalk. But even if the street or sidewalk is part of the lot, there’ll be an easement for a public right of way to cross the property.
That may be typical, and may be the width of the right-of-way, but it is definitely not universal. I know because my street is being redone* and a sidewalk is being installed (just on my side). Afterwards the street will be narrower (about 6 feet narrower**), so either the current width or the new width has to be not 66 feet.

* a second storm sewer line is being installed, as there is street flooding issues upstream.
** they are still allowing parking on both sides – it is hard enough now when cars are parked on both sides, it is going to be very tight after
That probably varies from municipality to municipality, and certainly by state, nation, or other polity. And even within any given jurisdiction, street widths vary greatly.
My town uses 30 feet. My property is listed as 300 feet deep but I can only use 270 feet.
For what it is worth, the brochure I got about my street construction says “The project involves narrowing the roadway width to 37 feet with new concrete curb and gutter”

My FitBit AI coach mistook my 32 mile dirtbike ride for a trail run and congratulated me on my 5:27 pace! If I could do that I could probably be world champion at ultr running…
Units? 5 hours and 27 minutes sounds too slow for 32 miles on any sort of bike, but 5 minutes and 27 seconds is way too fast.
5 minutes 27 secs. I was moving pretty good. 16 miles in 45 minutes on the way out, so under a 3 minute mile. Then my carpal tunnel flared up and I slowed wayyy down. What’s crazy is that the latest marathon record is at least as fast as that average.
4:35/mile
2:49 /km
Double-check that?
But yeah, 20 MPH at the start, then slowing way down, sounds plausible.
It also makes sense as exactly four laps of the track
There’s no ‘probably’ about it. After the fall of the GDR, researchers looked into the state-run doping regime that took place from the mid-60s. They discovered a letter written by Koch to the state doping authority, complaing that one of her rivals (also a GDR athlete) was receiving stronger does of steroids, because she had a relative working for the company.
“She’s cheating more than I am! It’s not fair!!!”
Of course I knew about the state-sponsored doping in the GDR, but not about that particular letter. Why didn’t they void her record after this clear proof of cheating?
The new record would most likely go to another cheater. It’s nearly impossible to determine a clean athlete who should have the record.
Yeah, that’s probably the depressing truth I hadn’t thought about.
