Improved measurements to accurate numbers
[edit]I made the measurements more precise as this page showed inaccurate measurements.
For example 1 inch is 2.54 cm, which is 1.6% larger than 2.5 cm, 10 meters is 0.584% under 33 feet, and 12 inches is 1.6% larger than 30 cm.
Inches are imperial units and centimeters and meters are metric units, so they don't always relate precisely.
So a human hair with 100 microns (0.1 mm) thick means that 1 inch is 4 human hairs wider than 2.5 cm, and 12" is 48 human hairs wider than 30 cm, which means that 0.584% difference between 10 meters and 33 feet means that 33 feet is 584 human hairs wider than 10 meters. 33 feet is 10.0584 meters. 33 feet is 396 inches and 400 inches is 33.3333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333 feet, which is 16 cm, or 1600 human hairs wider than 10 meters. 10 meters is 393.7007874015748 inches, which equals 32.808398950131231 feet.
This page needed accurate values over the years since it's first been published. — Preceding unsigned comment added by NelsonEN24 (talk • contribs)
Maximum globe size claimed
[edit]The largest size globe mentioned to be on the market is known to be 70 feet in diameter, which is 21.366 meters.[1] It seems ridiculously large for a yard globe, yet hard for what appears for many to believe, but it was noted as the largest known on the markets. — Preceding unsigned comment added by NelsonEN24 (talk • contribs)
Why a slight error is a big problem in measurement systems
[edit]My 1st talk page logged in.
Measurement are fundamental and help us understand how big, small, long, short, massive, or heavy something is, along with the duration of time.
For things to be made, specifically precise measurements have to be made.
For example, 10 meters is 32.808398950131231 feet, or 32 feet 9.70078740157481434 inches, which is 2.29921259832 inches less than 33 feet, a 0.584% difference, which is small but substantial. 12 inches is 4 mm 8/10 mm greater than 300 mm (so 304.8 mm) and 1 inch is 4/10 of 1 mm greater than 25 mm (so 25.4 mm). Yet 10 meters is 393.70078740157481434 inches whereas a 1.6% increase means 400 inches or 33 feet 4 inches, or 33.3333333333333333333333 feet, or 10 meters 16 cm, or 10.16 meters. That's a difference of 6.29921259843 inches, which is more than half a foot. Again that maybe small but substantial.
10 feet is 4 cm 8 mm above 3 meters, 100 feet is 48 cm above 30 meters, 1,000 feet is 4 meters 80 cm above 300 meters, 10,000 feet is 48 meters above 3 km, 100,000 feet is 480 meters above 30 km, 1,000,000 feet is 4 km 800 meters above 300 km, 10,000,000 feet is 48 km above 3,000 km, 100,000,000 feet is 480 km above 30,000 km, and 1,000,000,000 feet is 4,800 km above 300,000 km, the list goes on.
Metric units are NOT the same as imperial units and don't necessarily connect together. 500 mm is half a meter, which is 19.68503937007874 inches, or 1.6% smaller than 20 inches which is 508 mm. An inch is defined as being 4/10 of 1 mm greater than 25 mm.
Yet if a ball bearing ball were built to fit a ring with a 25.4 mm hole, then the ball has to be 25.4 mm in diameter or a 25 mm would fall off and not connect in place.
Plus some amusement rides have minimum height requirements, like for example on a roller coaster with a 48" height requirement, the person has to be Exactly 48" tall, or else a person even a millimeter or nanometer or 1/10th or 1/100th or 1/1000th of that below the height requirement (even a 47.999999999999999999999999999999999999999999 inch tall person) won't be allowed on the said ride, all for safety reasons, so precision is very important for amusement park rides and practically everything.
People who learn math have to be very accurate to get good grades and testers have to be precise to pass their tests. Yet astronauts have to do perfect on space missions. All of those show us that even the slightest most minuscule error can cause HUGE problems.
Just the tiniest flaw on missions ruin them completely, and in cases, can even tragically cause fatalities. Plus when a capsule docks onto a space station, the angle has to be precise to connect properly or else it would crash and the damage would be catastrophic.
If 2 lines were drawn, and the 1st one was 999 mm long and the other were 999,000,000,000 mm (or 999,000 km) long, the 1st line would be 1 mm less than a meter in length and the large one would be 1,000 km less than 1,000,000 km in length. A country can fit in a 1,000 km area, so even a tiny error is profound. Yet if a person were to swim 1,000 km and only swam 999 km, then he/she would be 1 km or 1,000 meters from the finish line, which is still MUCH bigger than any recreational swimming pool in length. 999 is much closer to 1000 (1000 - 0.1% is 999) than 300 is to 304.8 (300 + 1.6% is 304.8)or 305(300 + 1.666666666666666%).
Pages have to be completely accurate to be honest for people to understand, yet 1 tiny error can lead to confusion and even bigger problems. Just a TINY error is a BIG deal.
Some people think improvements are wrong when they're actually necessary and those who don't like precision are like saying people don't like others to tell the truth because telling the truth is the right thing to do when in fact lying is the wrong thing to do. In other words, precision is like telling the truth, we have to be honest or else we'd have trouble, and the slightest errors spell problems than can be and often are profound.
Articles need improvements for better accuracy and help people learn more what's true and what's not.
Reverting to imprecise values is the real mistake and improvements are solutions.
Now they could've mentioned tolerances, or how much dimensions XYZ vary from one another, which is still better than inaccurate page values. — Preceding unsigned comment added by NelsonEN24 (talk • contribs) 01:45, 12 June 2019 (UTC)

Wikipedia needs to improve their measurements
[edit]However conversions showing inaccurate values will only create more conflict rather than help. Measurements have to be accurate, and like I said, a 1.6% difference is not negligible, but actually substantial. Earth for example is almost 43 km wider at its equator and almost everybody knows that and that's just slightly over 0.3%. Much less than 1.6%. Wikipedia seriously needs to improve their conversion tolerances.
The inaccuracies of automatic conversions on Wikipedia pages including this
[edit]It says on the page that 12" is 300 mm which isn't true, because 300 mm is 98.4251968504% of 304.8 mm which's in fact 12". The difference between the " and mm conversion on Wikipedia is in fact very slightly more than the difference between someone who's 5'11" (1803.4 mm) and someone who's 6' (1828.8 mm) in height, plus 1800 mm is 5'10.86614173228346" which's more than 5'10" (1778 mm) but 3.4 mm less than 5'11" (1803.4 mm). Not to mention 1" is 25.4 mm, 10" is 254 mm, 12" is 304.8 mm, 24" is 609.6 mm, 36" is 914.4 mm, 48" is 121.92 mm. And 10 meters isn't even 33 feet, but 32'9.7007874015747965757", because 33 feet is 10 m 5 cm 8 mm 400 μm. We can't have a number that doesn't match the value no matter how we view things including objects or people. Wikipedia needs to improve their automatic conversions in measurements and it would help a lot of people learn and get smarter. Even for pages like this (about yard globes).
