Sea water or fresh water?
With 125% tariffs, will the e-bike market die?

I know it was a rhetoric question to check Uma's knowledge
Fresh water at 4 degrees Celsius.
There were more water based units such as calorie. The specific heat of water is 1 kcal/kg-C. The metric system uses kJ/kg-K though.

So with rising sea level will things weigh more and be longer or converse?

With rising sea level the entire system will be trashed. You would need to recalibrate everything for Everest, even conversations like this would become less dense.

the originators used a decimal unit for the meter,think it was from the equator to pole( they were French check your history. Google it of course its more precise now.I know it was a rhetoric question to check Uma's knowledge

Of course. It is still a mystery for me why a cubic metre of pure water at 4 C weighs exactly 1000 kg or the viscosity of water is exactly 0.1 N-s/m^2 (0.1 Pa-s) at 20 C
Kevin, why is the American unit of heat named British Thermal Unit BTU, and when will the POTUS rename it to ATU?

shhh! dont give him any ideas,that guy is gonna "boom or bust" this country( to-whit-to-whitOf course. It is still a mystery for me why a cubic metre of pure water at 4 C weighs exactly 1000 kg or the viscosity of water is exactly 0.1 N-s/m^2 (0.1 Pa-s) at 20 C

To make it even funnier, the word "ATU" (short for 'atut') means TRUMP in Polish. Like in jeden bez atu (One No Trump, 1 NT) in the card game of bridgeshhh! dont give him any ideas,that guy is gonna "boom or bust" this country( to-whit-to-whit

I've been seeing a lot of that as well, especially bike parts. Prices have risen but often they straight up won't ship to the US. I needed a part for an Ltwoo groupset and managed to get it in before s*it hit the fan, but it did sit in Baltimore for like two weeks waiting to clear customs. If it doesn't work or I need something else I imagine I'm just screwed and will need to replace the groupset.
For other things I participate in that has some AliE component, some companies have been routing through the Netherlands to try and avoid tariffs, and some have just raised prices 50-100%.

I wanted a quote from a supplier I have had a great relationship with for years. He even sends me some personal stuff too like vacation stories, as I share things with him. He is usually right on it with a professional quote back to me the next morning. I asked for a quote on Thursday and nothing. Maybe he is just taking May Day week off. Or they will not even talk to people in the US anymore. Can't blame them. If that is company policy and maybe even official. When you give someone the bird, what do you expect.
Oh, I forgot to mention that with sea level rise, pitch will change, like Cheech smoking a helium bong, and there will be time dilatation. A bong hit would help before reading this article.

If "things" were not in the water, but now are, they will weigh less; their dimensions won't change unless they are compressible.So with rising sea level will things weigh more and be longer or converse?
What system?
Regardless of the system you think will be trashed, think of the possibilities: turn Miami into the Venice of Florida! Cha Ching!!

I am such a bike geek! I just told this to a client to the north. I am guilty as accused for my total bike geekdom. He got a super premium battery from me that arrived today and he just barely skirted the 145% new taxes. I am walking him through all aspects of the custom build of, to a geek is, a totally cool build with a palm sized 90Nm quiet motor.
You got the battery! Look on the underside of the battery holder/tray. There are three small #2 Phillips screws, another Harbor Freight pick-up for the small driver at $3.42. Remove those three screws. Under that plate is where you will solder the power leads directly from the motor. Get the length right and seal the motor power leads with about one foot or so of ¼ inch tube. It is like little kids playing with beads in a row. Line it all up. Red long to short, black short to long. Twist and solder each. One to up, one to down, left and right. Solder. Seal each with marine grade tube then move up the other ¼ inch shrink tube, about 30mm long, to cover all and reattach the cover plate. It helps to have the upper screw of the battery holder/tray part way in so it swings. Plan out the whole bead string before any soldering. Think twice and thrice. It will take four pieces of ¼ inch shrink tube. One long to insulate the wires from under the motor cover plate to the underside of the battery. Two, one for red and black solder joints, and one to seal the up and down wires inside the curve of the cover plate. Make sure the bottom cover plate hole is part of your little kid’s bead string. It will go up and the three screws will be set. Clean.
