@xek @LovesTha where are you, that kilometres are in multiples of eight? I’ve never seen that.

@mhoye @xek 80kmph is a pretty common speed limit. Knowing that is 50mph is handy.

@LovesTha @mhoye @xek it's km/h There is not such thing as kmph unit!

@cpontvieux @LovesTha @mhoye @xek Kmph, while not official/scientific notation (as in notation encouraged by the SI) is apparently a widely used abbreviation. For example, see the link below.

It's potentially interesting (context dependent) to make people aware of SI conventions. Possibly not so useful to scold people on social media for employing widely used everyday alternatives in an "everyday" context?

@level98 @cpontvieux @mhoye @xek kph would irk me, thousands of what per hour? As does KMPH, case does matter.

(using a capital K at the start of a sentence is an awkward argument about which norm is more important)

@LovesTha @cpontvieux @mhoye @xek "k" for "kilo" as in "thousands" is lower-case.

The "official" notation, as mentioned by Cyrille, is:

km/h or km h⁻¹

If you (or anyone passing) happens to be interested / are not already aware... the organisation who determines such "official" things is the BIPM. A description/documentation of the SI system of units (overseen by the BIPM) can be found on their website.

km/h is not an SI unit... just "accepted" for use with the SI.

@level98 @cpontvieux @mhoye @xek Yes, techically KMPH is Kelvin Mega Pascals Hecto

Level 98

@LovesTha @cpontvieux @mhoye @xek Pascals is Pa, but that;s close enough for comic effect! 😆

"Kelvin Mega" could be a death metal band?

@LovesTha @mhoye @xek 80 km/h is common? At least here in B.C., most cities have it be 50/60/30 km/h, and 80 km/h is left to highways, maybe some freeways.

@mhoye @LovesTha In some American-authored stuff, maybe some UK works as well, places wind up being 40 or 16 or (my favorite) "about 24" kilometers away surprisingly often.

It amuses me to no end. What human would say "about 24" km instead of "about 25 km away? (Aside from Babylonians and other base-60 cultures.)

@mhoye @xek @LovesTha next time you're on the 401, check the signs for distances to the next rest stop. 160, 80 and 32 feature heavily. Pretty sure they kept the old sign posts for the new signs
