  • For length, for an average male one meter is about one large step with extended legs (useful for distances), or the distance between e.g. the left side of your torso to the end of the extended right hand (useful for estimating the length of rope or smth).

    For weight, it might be useful that 1 liter (that’s 1 dm3 but noone uses that except sometimes in scientific literature) is almost exactly 1 kg, and a typical cup fits 0.25 liter. A shot of alcohol is either 20 or 40 milliliters (0.02 or 0.04 liter) depending on where you are and what you order.

    For conversions you just need to remember the base unit (e.g. meter and grams/kilograms) and the decimal prefixes. But you really only need milli (1/1000), centi (1/100) and kilo (1000) in day to day life. Then you simply shift the decimal.

    Although you really need to consider the peer group you are working with, and make the contribution as little work as possible. In my experience, as soon as the course is over people won’t want to do any extra work like change the formatting or integrating with existing materials. And requiring to use a specific format (even if it’s something dead simple as markdown) might already be too much friction.

    In my experience shared cloud storage (GDrive, Dropbox,…) works quite well, even if the feature set is very limited. Being able to simply plonk your .docx/.pdf/.whatever into there is very easy and low friction.

    A different solution I saw that worked was a forum where you could also upload files that could be categorized into the different courses and were then accessible by others. If you were to self-host this, you’d really want to make sure somehow that it’s not exploited to spread malware or worse.

    Anyways, I wouldn’t think too much about how well the material can be represented, but rather how you can get your peers to continuously contribute to it. The best representation is useless without the data going with it.
