But literally every spec has a zero in the thousandths place, so really all the specs are rounded to the nearest hundredth of an inch. So, for example, if I measure .430 on my calipers, I hear people every day saying the dimensions are "four hundred and thirty thousandths," or that the spec for a given part is, "four hundred to five hundred" (meaning if the actual size is anywhere in between .4 and .5 inches, it's okay to pass inspection). I do it also, just because it's how they do it in the workplace, but it's interesting that nobody ever says "forty-three hundredths," and I'm pretty sure that if I were to start saying that then I would hear a lot of, "huh?" "What do you mean, four thirty?" and so forth.
Just call it a four-three calibre. If you want a longer sheet, ask for a four-three Magnum.

In which case, there is a huge market for calculators that default to decimal results. Just make it a setting!

As an engineer/surveyor, we work in decimal feet and meters. And that's US survey feet, not international feet.

When the international foot was defined in 1959, a great deal of survey data was already available based on the former definitions, especially in the United States and in India. The small difference between the survey and the international foot would not be detectable on a survey of a small parcel, but becomes significant for mapping, or when the state plane coordinate system (SPCS) is used in the US, because the origin of the system may be hundreds of thousands of feet (hundreds of miles) from the point of interest. Hence the previous definitions continued to be used for surveying in the United States and India for many years, and are denoted survey feet to distinguish them from the international foot. The United Kingdom was unaffected by this problem, as the retriangulation of Great Britain (1936–62) had been done in metres.

The only advantage the 'scientific calculator' still has is a battery life of weeks... and possibly being the only device dedicated to entering formulas (and therefore being less prone to crashing than e.g. android devices).

I challenge you to develop an ARM-based graphing calculator for about 100 <currency>. A quick look indicates you can get a good SoC for less than 20, a fucking touch screen for about 25 (note that's a 3.5 inch screen, so you have physical keys below), a decent lithium battery with controller for about 20 (you're not going to power it with a couple of AAA batteries*). So there's a bit of room for the buttons, casing and assembly.

*unless you find that dozens of non-rechargable alkaline batteries are more environmentally friendly than a single rechargable lithium-based battery.

NiMh seems like a better solution, depending on power consumption and weight requirements (I'm thinking button cell, so weight difference should be negligible).

I was just thinking of my past experience with putting rechargable batteries in the TI calculator, because they dropped below the required voltage quite quickly. But that is of course a problem of the TI calculator (and the choice of battery composition) and does not have to occur in our hypothetical calculator.

I guess the power draw will be about 2W. (the highest number on the LCD I could find is 3.3V * 0.15A and an efficient SoC draws about 1W tops) That sounds like a lot of cells in parallel to provide such current.
Going by the numbers on wikipedia, 100g of NiMH would give you 5 hours of continuous use, whereas 100g of Li-x would give you 12 hours.

Dammit, why does 2W sound like a small number to me? My smartphone has a ~4Wh battery and it manages to survive a whole week (provided I'm barely using it of course). That's like 25mW. The TV remote keeps working for months even! 2W is huge; it drains a pair of AA alkalines within 4 hours.

3.3v x 0.15a = .495W A factor of four off, but I was expecting a few orders of magnitude. This is of course peak power; devices last a long time when they are not used.

I'm finding numbers closer to half a watt for consumption smartphone displays; for a calculator, I don't think you need a super-bright screen, and you don't need a very powerful processor. I think you could get a decent calculator with 40mAh 1.2v button batteries, but this is out of my area.

If you're still giving latitude and longitude in degrees, minutes and seconds, they do have the advantage that ...

6,371 km * tan (1') = 1.8532488 km = 1.0006743 nm.

... one nautical mile per hour will move you one minute of longitude at the Equator or one minute of latitude anywhere per hour. Given a cosine table, you can multiply your speed in knots by "one minute of longitude at the Equator" by the cosine of your latitude to get your longitudinal speed.

2W includes peak power of the SoC and whatever other components in the calculator.
But indeed, that's peak power. When the SoC throttles down to nearly 0W, you're left with 48 hours of screen time for a 100g lithium battery (yes, still going for that battery pack rather than battery slots). That's not bad actually.

Awww, should've looked into modern graphing calculators: everyone's already offering touch screens for 100... plus margin, minus batteries, so maybe there is still something to gain. Especially with an ARM chip.

The availability of new smartphones for under \$100 retail suggests it's probably possible hardware wise. Does a cell radio and camera cost more than a more complicated case design and some buttons?

About two years ago, maybe, I saw a few news stories about a large hole in the ground that was found via aerial photography, in Russia I think (maybe not, but I think it was at least in Asia or Europe). The article said that the hole was in a remote area, but a scientific expedition was planned. Quite some time later (sometime in 2016, I think), I tried to search the web for a followup story, because I'm curious as to what the expedition discovered or concluded. My search was unfruitful. Does anyone know what I'm talking about? Can anyone help me find more information?
