Everything but the Metric System: “The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog.” :)

I wonder if Americans don't have a mental image for measurement units so that they alway use some physical object as a reference. Sure, its useful to use a common object as a reference but I don't see that much often in other places.

Most people usually understand what it means something to be 20 meters, 5kg or 2 liters intuitively. Like, when I hear that something is 60m tall I intuitively think if it as 20 story apartment building and don't benefit from the extra info about how this is like 18 elephants stacked on each other.

I guess you're in the minority here. In Germany, everything Remotely large will be measured in football fields or "Saarlands".

What's the difference between 18 elephants stacked versus a building with 20 stories? They are just different analogies.

Yes I'm always a bit dumbfounded by this behavior as well. They always use weird stuff and I never have the intuition of the actual size, especially since the definition can vary depending on context.

In this case, what is actually considered to be a small dog? To me it would be something that is close to the size of a cat but since it's about 13kg, it can't be that small, so that's more like a medium dog (I'm not certain, but I have a feeling that if you lay out things statistically this is what you would end up with). On the other hand, 13kg is very easy to get, that's just 13 liters of water, and it's quite easy to make a mental image for both volume and weight "feeling" that way.

American units feel so impressive and random, it is the reason they always add those weird comparisons but often they make it even worse.

Which is strange, since one of their measurement units is literally based on a body part.

Americans do not do metric. Americans can’t even balance a checkbook. Hence the small dog reference for mental “clarity”. We’re dumb. Just look at the news…

It helps to understand that the only freedom Americans only cared for (and the only freedom they have left from the looks of it) is the freedom to choose standards of measurement and vocabulary.

The link you're quoting, the one posted, is a second hand US report.

The primary company link is from a UK subsidiary of Mercedes-Benz and is (almost) fully metric (the fundemental units US weights are officially defined with respect to (for more than a century now)).

See: https://yasa.com/news/yasa-smashes-own-unofficial-power-dens...

  Earlier in the summer YASA achieved 550kW (738bhp) from a 13.1kg version of its new axial flux prototype motor, equating to an unofficial power density world record of 42kW/kg

  Now latest testing of an even lighter 12.7kg version on a more powerful dynamometer has shattered this record, with a staggering 750kW (>1000bhp) short-term peak rating, resulting in a new unofficial power density record of 59kW/kg
Just those pesky trad bhp units left hanging like a chad in a Florida election . . .

You can tell, because a proper Brit would have given it as 2 stone, not 28 pound.

If I were a self-respecting journalist, I would've used 3.26 gallon milk jugs. Small dog automatically goes to which breed? Chihuahua (fits in a toddlers purse) or Border Collie or Golden Retriever or Saint Bernard (needs an SUV/minivan)? 4 different classifications based on size!

Is even a 13 kg dog "small"? It certainly does not feel small if you are carrying it upstairs.

It's American small.

mattmaroon|3 months ago

While there’s no formal definition, I think it isn’t. It would be considered medium sized. I live with a 4 lb dog.

I’d say 25-50 lbs would be medium, small below that and large above.

Imperial dog or metric dogge?

Americans are very weird when it comes to metric. They often quote mobile phones as having something like "a six inch screen size but now only 12mm thick" - pick a measurement system people !

huhtenberg|3 months ago

Canada is even weirder.

After switching to the metric system ('70-80s) some things are still measures in imperial units. If you slice some ham at a counter in a grocery store, it's in grams. You then turn around and get a pound of apples and a gallon of milk. Nuts are in grams, and soda is in liters. Also the body weight tends to be in pounds. Tools are both metric and imperial. Speeds and distances though, thank god, are metric.

All this is just kinda there and everyone's OK with it, but it is an epic mess if you think about it.

The inch thing is because it's a screen: all screens are measured in inches pretty much everywhere, even in the EU

I like having more choices for units. Sometimes the "correct" unit is extremely inconvient to deal with, either because the unit sizes are oddly out of proportion with the things being measured, or the things being measured have odd ratios with the units. Sometimes even making your own unit system or going with pure ratio relationships between objects is the most useful and effective way to measure things. And I feel that people who only ever use a single system of measurement often fail to see it and put themselves at a large disadvantage.

To me using only a single system of measurement is the same as only ever using a single number base. Yeah it helps to have a standard number base everyone can use like base 10, but that doesn't mean we should try to eliminate other number bases from our vocabulary or understanding because they obviously have situational advantages.

Also from my personal bias I much prefer fractional measurements and people go apeshit if you use fractional metric units but don't blink an eye at fractional imperial or other 'non-standard' measurements.

Bag of potatoes?

If you mean a 13kg bag of potatoes, then I'll allow it.
