Fun fact, they short changed the horse:

Over a short period of time, they calculate, a horse can exert up to 14.9 horsepower.

[–] Catoblepas@lemmy.blahaj.zone 59 points 11 months ago (1 children)

Wasn't horse power intended to represent the average energy output of a horse over a working day, rather than a brief maximum?

[–] Ilovethebomb@lemm.ee 24 points 11 months ago

Yes, it was.

[–] WoefKat@lemmy.ml 54 points 11 months ago (1 children)

How much do you weigh? As much as 11 stones and 2 pebbles.

How far is that? 2 feet and 5 thumbs.

How fast are we going? About 6 knots in a rope that's hanging overboard.

It does make me laugh sometimes sorry. But the real problem is not the base units.. It's the multiplication factor.

I agree that most of the imperial system sucks, but knots (and by extention nautical miles) have a good reason for being used everywhere when navigating long distances around the globe because both are based on the way coordinates work.

My electric vehicle, when set to imperial, will display charging speed in horsepower.

Apparently a wall outlet can provide 3.2 horsepower.

[–] name_NULL111653@pawb.social 21 points 11 months ago

Checks out, that's 2,610 watts, or about a 20A circuit at 120V.

Giving me horsepower for the motor output instead of kilowatts kind of makes sense, but it changes everywhere.

The battery just displays as a percentage, otherwise it might tell me the energy remaining in horsepower hours.

[–] SuperSpruce@lemmy.ml 37 points 11 months ago

That's 149KW (200hp) on that tiny car? That sounds like a hoot to drive

Ironic.

The American truck complaining that the EU is too regulated, while in the US something as simple as headlights are so overregulated they blind people while driving.

In the EU the headlights simply aim their lights away from incoming traffic automatically, which was a crime in the US until like last year.

That only works like half the times at best. I'm still constantly getting my eyes lasered by big ass SUVs while driving at night. Not even counting the people that have misadjusted headlights.

[–] korewa@reddthat.com 3 points 11 months ago

Which cars do these now in the US?

[–] glibg10b@lemmy.ml 27 points 11 months ago (2 children)

1 Nm/s = 1 watt. It's a measure of power, not force

[–] spicystraw@lemmy.world 4 points 11 months ago (1 children)

So is horsepower, whats your point?

[–] glibg10b@lemmy.ml 12 points 11 months ago (1 children)
[–] spicystraw@lemmy.world 3 points 11 months ago

Ah, thats true, didn`t read the meme properly the first time.

[–] DrCatface@lemmy.ml 2 points 11 months ago* (last edited 11 months ago)

sorry pocket reply

[–] Granixo@feddit.cl 24 points 11 months ago* (last edited 11 months ago) (2 children)

Ok, i'm gonna be that guy.

Newton meters (Nm) is a measure of torque.

While horse power (HP) is a measure of engine power.

You obviously cannot convert one into the other because they mean different things.

Also, when EVs eventually become the mayority, the kilowatt (kW) is gonna take over as the new standard for measuring engine power.

[–] name_NULL111653@pawb.social 10 points 11 months ago

N*m/s, not Nm. That's energy in joules. Still not power (J/s, which can convert to HP) though...

[–] Venat0r@lemmy.world 7 points 11 months ago

I think that's the joke: Americans don't care about efficency, only power.

[–] reverendsteveii@lemm.ee 22 points 11 months ago (1 children)

Thing is, one horse tops out at about 15 horsepower of force.

[–] Bytemeister@lemmy.world 13 points 11 months ago

15 ANSI horses, or 15 ISO horses?

[–] workerONE@lemmy.world 20 points 11 months ago

It's a waste to make a 500hp truck when you could make two 250hp trucks instead

[–] AI_toothbrush@lemmy.zip 17 points 11 months ago

Op truck because one horse is up to 15hp. That truck would be 7500hp 💀

[–] threethan@reddthat.com 15 points 11 months ago (1 children)

I made this as a total shitpost but I'm loving the informative comments. Godwin's law at its finest.

[–] cupcakezealot@lemmy.blahaj.zone 3 points 11 months ago

congress should introduce all bills originally as shitposts

[–] Venat0r@lemmy.world 6 points 11 months ago* (last edited 11 months ago)

Wow, that truck must have about ~~7,450hp~~ 2,850hp ! 😲

[–] ThePJN@sopuli.xyz 5 points 11 months ago (2 children)

Bah! Most people have never even seen a horse. I never would have, had we not been dragged to see the pervert horse ballet when it came to town.

A fellow PHB enjoyer, I see!
