Talk:KPH

Whimsical abbreviations

• kilo-parsecs-an-hour (8.6 exametres per second, or 28.6 million times faster than light)
• kilo-pH (extremely strong alkalinity)

kilo-pH is interesting, as I believed the scale could only go from 0 to 14. However, this article says that:

"[The pH scale ] describes how many hydrogen ions (protons) are present in a solution. [..] the higher the pH, the lower the hydrogen ion concentration, and vice versa. But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero. For example, concentrated hydrochloric acid can have a pH of around -1, while sodium hydroxide solution can have a pH as high as 15."

Is it even possible to achieve 1 kilo-pH? Sauer202 (talk) 15:14, 18 November 2019 (UTC)

A conversion from MPH

A certain American publication uses abreviations kph or even k.p.h. to convert from miles per hour to kilometers per hour. where wouldb these atroceties orriginate? Are they cute American inventions, or were they used elsewhere in premetrication times? Peter Horn User talk 00:40, 30 November 2022 (UTC)

I'll restate my question. Who invented kph or KPH as an abbreviation for kilimeters per hour and where? Peter Horn User talk 19:22, 3 December 2022 (UTC)
