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.

The real guide is still either outdated or doesn’t take into account that there’s a lot more steps. But considering it’s been 2 years, I don’t hold that against the author

I think that’s too simplified and it will create expectations that aren’t true, because It’s more like this:

1. Choose instance

2. Read & agree to Mastadon rules

3. Read & agree to (instance) privacy terms

4. Create account

5. Tap the verification link in your email

6. Solve the Captcha

7. Get a list of people/users to follow (why these people? What is it based on?)

8. Setup profile

9. Done!
