Today I discovered that our car is showing petrol consumption usually in liters per 100 kilometers which is the common measurement (miles per gallon in the US or UK) but shows liters per hour when standing. Probably all cars do that and it is totally logical to engineers why it has to be that way but I never realized.
From a technical perspektive it seems logical to make a difference in the measurements as one can hardly measure distance when standing but thinking about it, it even fits the users perspektive.
When driving along especially when covering bigger distances we tend to think in distance covered or to go. In a city something like only around that corner and then the second to the left and two more lights. Outside town something like 150 kilometers to go or on longer trips: “Finally only double digit kilometers to go”.
When sitting in a traffic jam on the other hand side we tend to think in time. Already lost an hour. Or took me twice as long to get to work today due to traffic. So the different meassurements make perfect sense not only from a technical perspective.
Navigation systems also show both values distance to go and approximate arrival time. Curiously here one is consistant whereas the other can change. Distance to go will only ever change if the route is calculated again due to changing conditions. In this case distance might grow whereas time decreases again. Here as users we will weigh both against each other to decide if we follow the new route or stick to the old.
Seems like actually both measurements and their value depend on context a lot.
Reminds me to always consider the users context when developing or especially texting for products.
