From the description of the Acrobatics skill:

Quote:


The base DC to make a jump is equal to the distance to be crossed (if horizontal) or four times the height to be reached (if vertical).

Since no units are given on "the distance", I assume we work in the most natural units, i.e. Planck Lengths. So, a jump of five feet would have a difficulty class of 9.4x10^34.

Sound about right?

Um back when I studied science the SI unit of length was the metre.


What that hell is a met-re? Here in 'merica we use feet. Cause you got them on you all the time.


What is this gobbligook I'm seeing? Every grognard knows that the one true unit of measure mean is the all mighty square.

As an astronomer, I would prefer to use the parsec. For the sake of game balance, I am willing to scale it down to the light year, or even all the way down to the AU.

Not even close. Open the skill back up, scroll down to the tables marked Long Jump and High Jump. Those are what that sentence is talking about.

I always have my d(googol) handy.

You are no true grognard. If you were, you would know that the true measure of distance, according to the testimony of Gary himself, is the ". The length of an " changes according to whether you are inside or outside.

To scroll my rulebook, I'd have to rip the pages out and that seems a bit extreme.

As to units of length, it was established at my high school that the non-scientific universal unit was [insert colloquial name of part of the male anatomy not usable on this board] length with the abbreviation dl.

And, the only problem with that length of measurement is variability.

Hence the un-scientific nature of the unit. The foot (and the cubit etc) as a unit of length started off the same.

Anyway this thread is too profound for me, so I'm off to see Transformers.

Wait, are we talking about wieners? You can't just go around talking about wieners without saying wiener. Its not right.

Since when is dick not usable on these boards?

It's a common used measurement.

I believe it is a base 5.6 inches.

Why do you need to measure torque over time?

Because we have a lot of forum trolls and have to measure how quickly they anger people?

It could be not only applicable, but vital to such builds as trippers, disarmers, and grapplers. *nods sagely*

I thought troll-anger-rate was measured in millicarbombs (1000 mcb = the amount of rage you must feel in order to make it your life's goal to track down the troll's physical location and install a bomb in his car).

I thought it was measured in Force Chokes; the amount of anger it takes for your hate to manifest as psychic powers and throttle them.


I think the absolute BEST unit is that of fuel consumption.

(Using SI) 1 liter / kilometer can be expressed as cubic decimeters / kilometer, or 0,1 * 0,1 * 0,1 = 0,001 meter3 / 1000 meters.

Divide by a meter above and below, and you get 0,001 meter2/1000 = 0,000001 meter2, or 1 square millimeter. The fuel consumption of a car can accurately be described using the unit mm2. TA DAAAAH!

Which is why when you learn dimensional analysis in chemistry they teach you that it is not enough to keep track of units, you must also keep track of what the units are OF. So, you have dm cubed of fuel over kilometers of (nothing) so you do not have compatible units for canceling.

Oh... ... Wait... I mean in 'merica we use gallons and miles! Take your French fru fru numbers and get out!
