  • We don’t really need any of those mnemonics because it’s a perfect system

    More seriously there is the “King Henry Died, Drinking Chocolate Milk” for the Kilo (1000) Hecto (100) Deca (10), Deci (0.1) Centi (0.01) Milli (0.001), but that doesn’t really help with measuring on the spot, aside from being able to get the prefix right.

    There’s an average step being 1 meter, but thats less useful for people with shorter legs unless they want to join the ministry of silly walks.

    One that I use often is converting meters per second to kilometers per hour. Because 1 meter per second is 3600 meters per hour or 3.6 kilometers per hour, you can actually skip the multiply by 3600 and then divide by 1000 and just multiply by 3.6.

    But aside from time conversions, there isn’t really anything else that can help because it’s just moving the decimal.

    Slightly related, you can tell how far away lightning is by listening for the thunder and counting the seconds. Sound travels at 346 m/s so every 3 seconds is roughly 1 kilometer away. But I suppose you can do the same for miles and count to 5.











  • rather than just spamming memes and non sequitors based off keywords in the topic title

    Yeah I thought that was just reddit, but we do it over here too. Stupid thing is, the “karma” or whatever it’s called on Lemmy isn’t even displayed, so it doesn’t do shit anyway.

    I probably should have been nicer and not done the LMGTFY

    I mean, maybe? I think if all the downvoters understood that the content in question was right there in the article, they would have been on your side. Instead, they just pile on and call you a meanie. Meh.
