Sorry for being pedantic, but those foldable work rulers are exactly 2 m long (at least in MetricLandia), which is, incidentally, the span of IQ values (0-200).

So yeah, it literally can be mapped one-to-one to a (common type of) ruler.

This is a common ruler where you live?

In my country we have rulers with 12 in/ ~30cm as the most common. We also have "yardstick" which is more often a meter stick now. But no foldable rulers.

Yeah.

The 30 cm is ubiquitous for officework or drawing, while this is for tiling floors, doing plumbing, measuring walls, roofs, etc. etc.. There are also those retractable coils (usually 2 or 5m), but they tend to break easily and collapse under their own weight, so they're not as useful for some things.

I can find one like this in basically any hardware store with few exceptions (Austria). They're almost exclusively 2m in length (I literally haven't seen a longer or shorter one ever in my life)

Also, a meter stick sounds workable, but borderline impractical.

Yup. There are like 3 types of rulers: normal (a stick), foldable (this) and those retractable metallic strips.

Sticks are usually either 15 or 30 cm, while the foldables are literally always 2m.

The coils are the most ubiquitous, but I orefer the foldavles for most things since they tend to fall undet their own weight when measuring longer distances. These sre either 2 or 5 m I think.

We have the coils too, except we call it a measuring tape.

We also have have a flexible soft version used for measuring human proportions for clothing, but it's called a "tape measure" for some reason.

I wish we had the foldable kind, that sounds useful.

200cm, the american one is up to 80 inches 😁
