IDK if you're still here or if this might help, but in the most recent edition of 5e, carrying capacity is calculated by 15* strength score. The limit for what you can push, drag, or carry is twice that number. So, say a duck has 3 str- it can carry 45 lbs. It can push/pull/carry 90 lbs.

For comparison, a Draft Horse has 18 str. It can carry 270 lbs, and push/pull/drag 540 lbs.

Of course, there's no actual statblock for a duck in 5e's monster manual, but you could probably use the 3.5e statblock just fine.

I take it you're not going to attach ducks to mill wheels to measure their horsepower?


For the purpose of a game where I'm not a complete madman, I'd just take a ratio of duck's medium carrying capacity (10lb for a 3 strength tiny bipedal creature) to that of a heavy horse (400 lb as per statblock), and take that as the horsepower they can output. That would be 1/40 horsepower, which still sounds a little high.

I think I would also multiply that by the ratio of their medium-encumbrance movement speed. A heavy horse moves 35 feet in that condition (it's 50ft unencumbered), and I don't know what a duck's land speed is. If we assume the duck moves at 5ft per round while encumbered, then the ratio of movement is 1/7, leaving the duck at 1/280 horsepower.


tl;dr: With extremely crude back-of-the envelope calculations and a shaky understanding of what horsepower actually represents, I propose that it should take 280 ducks to generate 1 horsepower.

In GURPS, a duck can push a 7-kilogram object across a relatively smooth surface at approximately one meter/second. My knowledge of physics is very rudamentary, but going by those (incredibly ballpark-y) figures, that duck is putting out about 7 watts, or roughly one-hundreth of the horsepower of an actual horse.

>tl;dr
>One duckpower = 0.9333 horsepower
>One horsepower = 107 duckpower

Hitching those ducks up to a wagon or plow would have its own issues, of course, if only because of the difficulty in getting over 100 mallards to walk in the same direction... in unison... carrying a weight on their backs.

>So, say a duck has 3 str- it can carry 45 lbs. It can push/pull/carry 90 lbs.
You forgot size modifiers. A tiny creature can carry half, and a large creature can carry double.


So the duck would carry 22.5 pounds, and pull 45 pounds. A horse would carry 540 and pull up to 1,080 pounds.

>One duckpower = 0.9333 horsepower
And that's a typo; it's 0.009333 horsepower. I originaly wrote out the differences as percentages (One DP = 0.9333% of one HP) and changed it later.

In D&D 3.5, a horse (heavy) is a large quadraped with a Strength score of 16-18 (depending on combat training). This gives it a light load of 230-300 pounds.

A 3.5 duck is a tiny biped. With 3 Strength, it has a light load of 5 pounds.

Thus, 1 horsepower = 46-60 duckpower.

That show was pretty great.

/tg/ getting shit done!

>>50126425
Wouldn't the creature's speed have an impact on horsepower?

>>50126400
If you put 20lbs on a duck you'll kill it.

>>50126425
This sounds about accurate

>>50130274

Not directly. Horsepower is a measure of strength, while speed is a result of strength applied against weight and resistance.

No, horsepower is a measure of power. Strength is a very vague term that means whatever the DM wants it to mean.

The difference might seem pedantic, but it's really not. Power is work/time.
1 horsepower is equal to 550 foot*pounds/second. That means that it takes 1 horsepower to raise 550 pounds 1 foot in a second. Alternatively,you could lift 1 pound 550 feet in one second. Either way, it is a HUGE amount of power (compared to human power output)

>1Hp=280 Dp

>>50126425
>1Hp=46-60 Dp

None of these faggots even showed their math. We're going to work this out better.
Firstly, let's get our values
1DP= ?
1HP= 550 (ft*lb/s)

I don't have a bunch of ducks to strap to a millwheel, but you said this is for D&D, so we can just use those stats. Most horses have a STR score between 15 and 20. We can take 17 as our horse STR value. No ducks, but ravens have STR score of 2, so let's use that.
Hstr=17
Dstr=2
For light load comes out to
Hlift=Hstr*5=17*5=85
Dlift=Dstr*5=2*5=10

Move for a horse is 50ft/6sec=8.3ft/s
Move for a duck is probably about 20ft/6sec=3.3ft/s

Hspd=8.3 ft/s
Dspd=3.3 ft/s

Now to convert that into power
Hp= Hlift*Hspd=85*8.3=706 ftlb/s
Dp=Dlift*Dspd=3.3*10=33 ftlb/s

This is actually surprisingly close to the actual value, given how abstract D&D is a lot of the time. We can assume that both of these values are a bit on the high side, given that the system is set up to allow PCs to carry whatever they want. Let's make a coefficient to convert the real value

Game Horsepower/RL Horsepower=Power Modifer
((706 ftlb/s)/(550 ftlb/s))=
1.28=

Game Duckpower/Power Modifier Coefficnt= RL Duckpower
((33 ftlb/s)/(1.28))=
26 ftlb/s=

Thus
1 Duckpower=26 ftlb/s
And the ratio between duck and horsepower is:
1Horsepower=21 Duckpower

You are technically, correct ,sir. The best kind of correct! I concede the point.
Also, 5 star post, man.
