A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

I flew for the first time on a plane last week and I've seen planes take off at the airport. It looks crazy. But being on one is totally different like holy shit. The thing just FLIES. It just.... Soars... Through the sky! Like whoa man. Wtf... It's crazy. With how much these things weigh, it's insane to me the thing can just go up and bam, there we are, we're flying now. Like wow... Dude crazy.

Since when 1000kg is not equal to one tonne?

[–] [email protected] 8 points 5 days ago (2 children)

There are tons of tons, believe it or not.

There's the short ton (2000lbs), long ton (2240 lbs), and tonne (1000kgs) which are all measure weight. However there's also the shipping/freight/ocean ton which is a measure of volume (which is also different in the US and UK), and the register ton.

However I did make a mistake. The wikipedia page I was reading said the weight in t and long tons. I made the mistake of assuming they meant short tons - in reality when measuring displacement for a ship, tonnes are used (which is pretty sensible, considering you're displacing water and a liter of water to a kilogram of water have a pretty easy conversion formula formula...)

I see, the common "Americans will use anything but SI", but in this case it's also the Brits lol

Thanks for explanation

Ton (imperial) is 2000lb vs tonne (metric)
