Customizable display type when showing grades
At the moment grades are displayed as 1/1000 (per mille) but other parts of the globe prefer percent or ratio.
It should be handled similarly to units (inch/feet/cm/..)
Now available in RailModeller Pro 5.3.7
Added for RailModeller Pro 5.3.7
Grade input/output will be configurable with the 3 most common notations supported initially:
- per mille (common in Central Europe)
- percent (common in the US)
- ratio (common in the UK)
All to be added the same way Units can be customized via the app's preferences!
There are several ways to express slope:
- as an angle of inclination to the horizontal. (This is the angle α opposite the "rise" side of a triangle with a right angle between vertical rise and horizontal run.)
- as a percentage. In the U.S., this percentage "grade" is the most commonly used unit for communicating slopes in transportation (streets, roads, highways and rail tracks), surveying, construction, and civil engineering.
- as a per mille figure. This is commonly used in Europe to denote the incline of a railway.
- as a ratio of one part rise to so many parts run. For example, a slope that has a rise of 5 feet for every 100 feet of run would have a slope ratio of 1 in 20. (The word "in" is normally used rather than the mathematical ratio notation of "1:20").
This is generally the method used to describe railway grades in Australia and the UK.
