Google - what's the weirdest conversion you can find?

There was a recent thread similar to this but it only mentioned about the Google converter being versatile, etc.
So, how about a challenge? (Strictly for fun of course).
Let’s see who can come up with the weirdest conversion that Goggle can actually calculate. (Let’s stay away from fortnights and furlongs - those have been worked to death).

Okay, here’s my first entry:**
443.471026 (carats per US fluid ounce) = 3.0 × 10[sup]12[/sup] stones per (cubic nautical mile)
**
Granted, “carats per US fluid ounce” to “stones per cubic nautical mile” is a very common conversion we probably have to calculate every day but heck - we have to start somewhere.

Can we have a link? I can’t seem to find a “google converter”, but I’m tired, so that could be the issue as well.

3 (rods per millisecond) = 90 720 000 furlongs per fortnight

1 mile per gallon = 0.18731261 light-years per cubic mile

40 (angstroms per minute) = 1.30723765 × 10^-06 miles per year

42 (cubits per hour) = 4.31289616 × 10-08 Astronomical Units per fortnight

1 Imperial pint = 1.93417364 × 10[sup]-53[/sup] cubic Parsecs

The answer to life the universe and everything=42

Oops, I didn’t look at the other thread. Somebody already pointed that one out.

5 (furlongs per fortnight) = 8.50414967 × 10[sup]-11[/sup] Parsecs per century

For some reason, it won’t tell me 20 psi in ounces per acre.

According to the units program installed on my Linux box, 20 pound/in^2 = 2.0072528e+09 oz/acre.

In addition, 5 mi/hogshead = 1.1111089 league/barrel, which is something else Google choked on.

(units rules, Google drools! Svaha! :p)

3 000 (spans per lunar month) = 4 638 099.83 fathoms per millenium

I wanted to use chains, but no dice.

Oddly, Google won’t do 9.8 meters per second squared in miles per hour squared.

the speed of light = 3.72461748 × 10^18 inches per decade

Ah, but can anybody come up with unusual units that are roughly equivalent? Mine are within one order of magnitude.

Well Robot Arm, I decided to fool around with my original entry and came up with this handy dandy conversion factor:
1 carat per cubic inch = 0.183676559 stones per cubic cubit

Yours is slightly closer to equality though.

However, I think the units I chose were a lot more unusual.
Miles per gallon is a relatively common (though archaic) way of expressing gas mileage.
Does anybody measure density in carats per cubic inch or stones per cubic cubit? Well if they do, they now know how to convert it. :smiley:

Anyway, I like the challenge you have presented to the SDMB.

Okay let’s try to have conversions that are:

  1. Within a factor of ten of each other
  2. in the wackiest, most arcane, obscure units and
  3. can still be converted by Google.

    (cubic cubits surprised the Hell out of me. Google can really calculate that)

It does math on those odd units too:
(1 US bushel) + (1 US peck) = 0.46090966 cubic cubits
