It&#x27;s a bit off-topic, but kph is not common in my experience. I have a good explanation: this is metric, which is a very convenient system. If you want to express one measure against an other one, just use measure1&#x2F;measure2. €10&#x2F;meter, 25kg&#x2F;liter etc. You can be more verbose and replace &quot;&#x2F;&quot; with &quot; per &quot;.<p>Adding constructs like kph sounds like the reintroduction of foot and elbow sizes in the system. Please keep it consistent. &#x2F;end of rant
