No need to simplify this.

(F - 32) / 1.8 = C

C * 1.8 + 32 = F

I personally find the math just as easy to do accurately. For example, 87F -32/1.8 = 55/1.8 =~30.5C. Compare that to your approximate method, which would give 28.5C, which is just wrong

(Maybe I just got really good at this when working a public facing job with a lot of American tourists - they would ask what our celsius temperatures were "in real units", so I got quite comfortable converting the air and water temps. Fahrenheit never once became intuitive to me, though.)

For C to F you can often simplify the mental math by doing the multiply by doubling then taking off 10%.

E.g., to convert 31℃ to ℉: 31 x 2 = 62. Subtract 6.2 = 55.8. Add 32 = 87.8℉.

If you want to round the result to the nearest integer the subtract 10% step is a convenient place: 31 x 2 = 62. Subtract 6 (rounded 6.2) = 56. Add 32 = 88℉.

Yes, doubling then subtracting 10% of the resultant works because that is the same as multiplying by 1.8 :)

When going the other way and dividing, I similarly find it mentally easier to multiply by 10/18 (rather than just divide by 1.8)

> It's for just 50k vehicles, which means that the first 50k that get sent will be all Luxury high margin electric vehicles. [...] Why would anyone use there quota for cheap stuff?

If you find a better primary source, you'll see that the lower price vehicles are the only thing allowed at the low tariff rate:

The deal covers vehicles priced at $33,000 or less, and other cars sold at that price are already manufactured offshore

> Massive trucks are useful for construction.

No, trucks are useful, but a massive modern pickup truck is much less useful in the urban context than a standard pickup truck from 30 years ago. The bed size has remained the same, the outside envelope of the vehicle has ballooned massively.

> You should get better transit so less people have cars.

Toronto has a very high (for north america) transit mode share

I'm not disagreeing smaller trucks are normally better, but massive trucks are useful unlike cars.

Toronto has good transit for North America, but there are plenty of ways to improve it.

I can run faster than the TTC streetcar

> I can run faster than the TTC streetcar

Yeah, so can I - doesn't mean much. The streetcar is not where TTC excels in ridership, the subway and buses are.

faster is one good way to improve. There is a long list of othersi

Fuel is sold by volume, which is why volumetric fuel efficiency is desirable to the consumer

Fuel is sold by volume and fuel type; diesel is about 25% more expensive per gallon than regular gasoline where I am.

Correct - where I am it is cheaper most of the year, a bit more expensive in the winter.

And it is 10% cheaper than gasoline where I am (South-Africa)

> but was struggling (am still) to see how it relates to a wooden trough that merely holds cables.

Overhead Catenary [1] is a standard term, for a system that has two wires overhead - one suspended from the posts (forming a series of catenary curve), the other suspended from that cable at regular intervals (and held level relative to the track). The wood in Boston's system seems to replace the catenary cable.

You have an inbuilt assumption about the purpose of a street name. Compare it with addresses in Japan [1], where some streets don't even have names. I don't know anything about Pakistan, but i wouldn't be surprised if the street name is solely to differentiate within some small geographic area. Looking at street view[2] from a nearby real estate development supports this

This was a bit painful for me when I first moved to Tokyo, since the building I was supposed to move into was newly build, and not on Google Maps yet. I had to ask a very nice old lady where １９番１５号 was supposed to be, and it took 20 minutes of us searching to find the place.

First thing I did upon finding it was to add it to the map lol

Note that this setting (only accessible from desktop) also blocks spellcheck, a feature that absolutely does not need AI to implement

Not defending mozilla adding AI to firefox, but...

If you've tried chrome recently, you'll know that it's jam packed full with even more stuff you don't want. And the article lays out how to easily disable all AI in firefox (which you cant do at all in Chrome)

I'm very pleased that disabling browser.ml.enable doesn't disable local translation. I don't need a dedicated UI for chat bots, but I find local translation very useful.

Knowing the average of 108 W wouldn't help with knowing your peak demand, as fridges vary significantly from off to startup to running, so knowing the average isn't useful in that situation either.

It would be completely wrong for peak demand. I had to learn this the hard way. While the small fridge I bought only uses 80 W while running the compressor uses 800W+ for a second on startup which was too much for my off the grid inverter.

Aside from desiring a longer battery life, you'll likely be shocked to hear that some of us (non-iphone users) still use the Aux jack and the SD card slot too!
