[Bumber]

Unless you're this guy.

[King Zultan]

I'm pretty sure trying to fuck a spider will kill it or get a spider bite on your dick or in your vagina, and none of that sounds pleasant.

Nobody even tries any more:

The photo was taken from about 1.4m miles away (2.2m kilometres),

Spoiler: rant (click to show/hide)

M is for 10⁺⁶ (or 2⁺²⁰*) dammit! m is 10^-3.  It's NINE orders of magnitude difference!!! ARGHGHGHGHG

*Yes I went there.  All the "Gi-/Mi-/ki-" people can go pound sand and make some silicon.

I think you will find that it was being used as an abbreviation for "million", not a metric prefix. Look, it's not even attached to the unit, and you can't say "millikilometres". I mean, you can, but those are just metres. So, it's not wrong, it's just a completely different thing than you're thinking.

[scriver]

I think it's 2.2 metrekilometre

[McTraveller]

Oh I know the intent, I just think a lowercase m for that usage is anathema.  I'm a grumpy middle-aged man.

[Rolan7]

Yeah, you're not wrong.  It'd be nice if the public was more familiar with such standards.

Reminds me of a ridiculous Discord argument amount metric vs imperial units where someone was saying it's inherently unwieldy to describe a person's height in meters or centimeters.
Like
decimeters exist
And that's if you don't want the precision of centimeters (when inches are only 2.54x larger)
If you're aiming for an equivalent to saying someone's 5/6/7ft tall, I feel like decimeters are a better middle ground.  Or you just say 1.7 meters like I presume most people would.

[methylatedspirit]

Oh god, decimeters. I can still remember my Chemistry classes where I had to calculate everything in decimeters cubed. No, not liters, a unit that is identical to that, but literally "dm³". I asked my teacher about this, and she completely denied that liters and decimeters cubed were the same unit in all but name.

Also, I think 2 significant figures are good enough for most everyday applications. In base 10, that equates to log₂(100) = ~6, so it's a nice 6 bits of precision.

[Frumple]

... I. Don't liters and meters just measure different things outright? One's for liquids, the other not?

[Rolan7]

Sure, but a liter is a liquid measure defined as the same space as a cubic decimeter (1000 cubic centimeters).
I didn't remember it was that amount specifically though!

*And then that's ALSO a kilogram of water, under normal conditions!

[methylatedspirit]

Liters are specifically for volume, while meters are a unit of length that can be raised to powers of 2 or 3 to get area and volume respectively. Liters are based on meters, mind you. That's why the cubic decimeter exists and is the systematic (derived solely from SI units and prefixes) equivalent of a liter. However, liters are well-accepted at this point, and are officially accepted for use in the SI despite not technically being an SI unit itself.

[Arx]

A litre is in the most technical sense a unit of capacity rather than volume.

It's also a bad idea to use litres in real physical calculations because it messes with the dimensional analysis compared to just acknowledging it as a distance cubed.

Said shortly, litres don't exist in pure calculation terms.



My sad is that I'm now diagnosed vitamin D deficient, despite the quantity of fierce sunlight we get. Taking supplements will hopefully make me hate life less, but it's an extra tablet in the daily routine.

Oh, and I'm sure lots of people will think it's funny to make crass jokes about dicks.

[ChairmanPoo]

Well it depends. Medical grade vitamin D is usually a stronger dose and you dont take 8t every day...

[Ulfarr]

*Laughs in Hydraulics where "meter" is a unit of energy*

Honestly, there are so many strange units in common use, in pretty much all applied sciences that the only significance in such distinctions is purely semantics.

*Technicaly it's "energy per weight of flowing liquid" but in SI that just ends up to just meters.


 

[Kagus]

I am relevant to both of these discussions simultaneously, in that I recently did a rough estimate of my penile volume and have now resolved to only give my measurements in the form of tablespoons (Tbsp).
