Horsepower is a unit of power created by James Watt in the 1700's. Who knew all these years later we'd still be using a unit he developed to compare steam engines to horsepower. We'll go through Watt's back of the napkin math, discuss in simple terms what horsepower means, and look at metric horsepower as well: PS, CV, and the many other abbreviations. Whether metric or imperial, horsepower as a unit makes no sense at all. We'll wrap up the video learning what unit we should actually be using.

Horsepower = horsevelocity * horseforce

If you were Australian you would get to enjoy cars being rated in kilowatts as well as being upside down.
-
Conclusion: American horses are 1.4% stronger than everyone else.
-
Fun fact: "cv" means "cavallo vapore", or quite literally "steam horse"
-
"A horse could have more than one horse power." That's poetry, man.
-
A recommendation for the unit of complexity: A fenske = how many whiteboards you need to discuss a topic

As a 62 yo Australian (and ex-tradesman) I grew up with the old imperial system and then had to learn the metric system after we made the transition after 1970. I remember at first everyone kept converting metric units back to their imperial equivalent so that it made sense and had meaning. Over time you just understood what it all meant. Americans have yet to make that journey but believe me when I tell you that it's not a difficult journey and once you get there you won't look back. The metric system is in fact perfect. We've all moved on from using horses as our main power source so it makes sense to move on to a more logical system of measurement. Did you know that one litre (correctly spelt) of water weighs one kilogram... perfect!

Maybe James Watt was just horsing around when he came up with horsepower
-
I knew it!, the correct unit should be Llamathrust

>laughs in australian >remembers I'm not australian >proceeds to brag about my car making 61,500 duckpower

This is the most popular and thoroughly researched community college class I ever got into.
-
As an Australian, it’s so satisfying watching this video 😂
-
Should've said "Thank you for watt-ching" at the end
-
Hey Jason, we need your analysis on the SSC Tuartara's top speed record😂. I know several youtuber already making video about it, but I think you can explain it better..
-
the "watt if" joke definitely just earned you my subscription lol
-
"A horse could have more than one horsepower." Clydesdale: hello.
-
In Switzerland, actually I think in all of Europe the power of a car is most of the time mentioned in kW and PS (hp).
-
I'm counting 7 colors on the whiteboard and I see a few horses drawn as well. This must be serious!
-
S.I Units, its scalable in a easy to understand manner. 1000mm , 100cm , 1m etc...even in slow Africa we work on that.
-
Great video!! In fact, KW is the official unit used by car manufacturers and is also used to calculate vehicle taxation
