• I noticed on a Common Feats Reference blog on this wiki that the average punch travels 15 mph.

Quick google searches provide that the average male weight is 197.5 pounds, with his entire arm being 5.7% of the body weight, or 11.2803 pounds. But the kinetic energy of that is 115.035 joules, higher than the 40 joules that's considered the baseline average human here.

So I decided, "maybe I'm doing something wrong, maybe I'm highballing it and I'm not supposed to include the upper arm in a punch." So by only using the forearm and hand, I get a weight to body ratio of 2.52%, 4.98708 pounds.

.... That got me 50.8578 joules.

"... Maybe the speed is wrong? Maybe the guy chose a value too high?"

Nope. A quick google search reveals that the average punch is not 15, but 20 mph.... That makes the lowball 90.4138 joules and the highball 204.507 joules...

Are the baselines for human level, athlete, and street level too low?

• bump

• Yeah, probably.

• bump

• You should contact a Staff Member.

• le third bump

• Have you contacted one?

• I've contacted Celestial Pegasus for you guys

• Good

• He said you need to ask a calc member

• Here you have the list of calc members:

• The values of Human level stats were always arbitrary to me. I mean the only reason why Peak Human is 300 joules and not higher is because people thought it would be weird to have some weapons at Athletic Human level.

However, I have seen some profiles of normal female and they are 10-B, so using the average male to find the baseline can be wrong.

• I'm assuming this is a value from a hook punch.

Well hook is a rotational movement and since human arm is roughly a rod the actual kinetic energy would only be a thind of what you calced. So 38 joules as low endÂ and 68 joules high end

• They probably used a hook punch. The jab/cross punch of an amateur boxer has a speed of 8.1/7.7 meters per second according to this, which is slower than the supposedly average punch.

• Average male ain't 197.5 lbs for the world. It's for the US. We're a fat country.

• I noticed that the 136.4 average is for menÂ andÂ women, actually, not just a male average.

But this is fine to work with.

Even taking these new absolute lows,Â 2.52% of 136.4 =Â 3.43728 pounds. Moving thatÂ  at 7.7 m/s isÂ 46.2202 joules, and that's choosing the minimum possible values.

• That's 3 times less for the rotational movement as I stated above

• I used the mean mass of 62kg in place of the mean weight of 136.4 pounds, and got ~46.317 J.

So, unless we should actually be using the weight/mass of the entire arm, the 10-B baseline is fine as it is.

• @KingPin0422 Well, that depends entirely on if you put your entire arm's weight into it or your just your hand and lower arm.

• Kinetic emergy does not depent on the weight of one's arm and mass always remains constant. But one again punch is an angular movement so not the entire mass of the arm is moving as fast as the first. The velocity is actually much lower near the joint. For this shape KE with theÂ velocity of the fistÂ should be devided by 3

• Where does this 'division by three' come from?

• rod about the end has the 1/3 fraction. That ratio comes from the integration over the length
• That's moment of inertia formulaÂ

• I believe that values for human levels comes from the their power output, that I remember it to be 80-100 W; of course, this do not means much, as one we start to perform hard tasks their power output increase, iirc up to 1000 W (but don't really remember).

• The result feets into 10-B well enough if you calculate KE properly. Where's no need for any further explanation

• And this average value, is the average human (with no fighting experience), or the one from the average boxer?

• I also always thought that the baselines are way too low since given the weight of average hand being 5% body weight or so it means that humans would only need to punch at 18 mph to get to 10-A, and since the average speed according to this thread is 15 mph, they would easily be 10-B+ if not 10-A with faster punches

• I mean, doing a little of research, 20 mph is the speed of the boxer's punches, that is already around above average human baseline. What is the current value for boxer's punches AP?

• Antoniofer wrote: I mean, doing a little of research, 20 mph is the speed of the boxer's punches, that is already around above average human baseline. What is the current value for boxer's punches AP?

Boxers shouldn't be baseline 10-A though. There are a lot of other Athletes who can't punch nearly as strong as them since the boxer actually trains to strengthen his punches

• I have already given the explanation but every body keeps ignoring it for some reason.

Anyway, the more accurate way to get mechanical energy of a punch is to measure a pushing force of ones fist and then multiply it by the arm's length. The 1/2mV^2 formula doesn't work here

• @Ugarik

So what should we do here?

• That would make the energy of the average boxer to be 500-580 J (they usually hit with a strength of 776 pounds of force). In the other hand, that would make it 1/30-1/25 times baseline 9-B, where the same feat that draw that boundary is x2.9 times stronger than the boxer's punch force.Â

But boxers shouldn't be the baseline for 10-A since they train to punch with more force than most other athletes. They would probably be a higher degree of 10-A or else most Athletes would be 10-B, which kind of contradicts the name of 10-A as "Athlete Level"

• Never said they were, and according the the method suggested by UgarikÂ that would fall under 9-C; at the end, Athletic and Street level are just names and clasifications made by us, can easily be altered if it suits us better.

• So what is the new 10-A baseline? And you mean that Boxers will be 9-C now?

• Not even sure what they were before, from 10-B to baseline 9-B are realistic levels, changing from average, to in shape to in shape thatÂ have proficiency.

What do you mean by that? Dudn't really understand you here

• In short, I simply don't known in what level the boxers fall in, but I think currently baseline 9-C or a little higher.

• Current tier 10 borders are fairly accurate so nothing should be changed. And honestly I wouldn't consider it a big deal even if they where not

• @Ugarik

Okay.

@All staff members

Is it fine if we close this thread then?

• @Antoniofer what's the source for 550 lbfÂ pushing force?Â Because it doesn't sound realisticÂ

• Here. Although, I would prefer to known the exact sources (whose article doesn't have).

• More intortantly I would like to know what "pound-of-force" even mean as a measure ofÂ punching strength. Because sticking strengh is measured in units of work/energy like joules or foot-pounds. By pushing force I meant the forse you can apply continuously using your fist.

And if you want to get the result inÂ joules force needs to be expressed in newtons andÂ distance in metresÂ

• I mean, in real life force is what is used to measure the force of strikes, or in pressure in other cases, not energy, you're not going to find punches records measured in energy, is not an accurate unit to measure the force of punches.

• If they measure punching force as the unit of force they do it wrong. A punch is called powerfull if it can break stuff. Breaking stuff requires work of elastic deformation and creating work requires energy.

• That would be an issue cuz several scientific experiments of have those feats measured by force, energy measure changes, that involve several things and is pretty ambiguos, meanwhile force is to measure impacts and tearing, taht is more fitting.

The same feat that is the baseline 9-B is measured in force too, +1000 kgf, placing it ~2.9 times above those boxer records.

• Well yes technically where is fore gained by the momentum due to deacceleration. But I meant constant pushing force not this one. I honestly have no idea why scientists care about impact force more than energy since energy is the ability to create work

Anyway my point still stands. This is not the force that needs to be used for mechanical energy. Constant pushing force can not be nearly as high

• Is cuz force reflect damage, meanwhile energy doesn't, it reflect change and thus ambiguos and unaccurate for it to determinate what effects it have over the target.

Constant pushing strength wouldn't be related to punches tho, and OP's main issue involve them. Although yes, the force in punches is more than simply KE, but neither is does to divide the force by the arm length; generally the force comes from gaining momentum from the feets to the fist (like a motion wave or something like that).

• As much as I want to debate why I think KE is more accurate we need to stay on topic.

It would. You need to multiply that constant pushing force (in newtons) to length of the arm (in meters).

If you're pushing something with constant force the velocity (and therefore KE) of the object you're pushing will be constantly itcreasing over the distance. Work is defined in similar way by the way.

If you want to use force of the collision you need to multiply it by the distance the fist had traweled after the collision (then it was deaccelerating)
