The SI system is also based on the length of body parts though
The second is the length of a single heartbeat. During one heartbeat, the heart muscle consumes 1 J of energy, which makes 1 J per second, roughly, which is 1 W.
Also the 1 m is the length of the spinal chord. Some might not get the significance of the spinal cord and that’s fine but it’s the central canal in the body so there’s that. Edit: yeah yeah i get it it’s not the “official origin”. However i remember reading a paper where they discussed that the meter should be the length of the spine, but they didn’t outright wanna say it, so they searched for a natural circumstances that just so happened to approximate that.
Also i believe that 1 kg is what you can comfortably carry. Or about the amount of food (cereals) that a worker gets paid for a day of field work. Compare to japanese Masu.
I’m honestly astounded by the amount of misinformation in this comment.
Second derives from sexagesimal measurements of day and night cycles. Metre derives from early Earth measurements. One gram is the weight of one cubic centimeter of water.
yeah ikr but why is the second 1/60 of 1/60 of 1/24 of a day? early people in antiquity could have made it 1/60 of 1/60 of 1/60 instead, or just 1/60 of 1/60. What inspired people to divide the day that way?
if your heartrate is a lot above 60 bpm you should do more exercise, then the pulse slows down. a fast pulse rate is often associated with not getting enough physical exercise.
healthy pulse is considered 60 bpm to 90 bpm. some argue 60 bpm to 75 bpm is the green range, while 75 bpm to 90 bpm is the yellow range, while above 90 bpm is red.

It looks like you could do a quick search and find an answer yourself, instead of making stuff up.
first result (https://www.discovermagazine.com/why-1-second-is-1-second-227) does not explain it
nope does not seem like i can find it easily and quickly. so, what is the reason?
Didn’t say it would be easy.
But just to be clear here, why would I do your job? And is it the alternative that you make things up instead of educating yourself?
My heart doesn’t beat 60bpm and I can comfortably carry more than 1kg. Pretty sure My heart isn’t 1W either.

You do know that people used to be significantly shorter when they came up the meter, right?
