The later uses its own system, the former two use Imperial Units. Apples documentation says (emphasis mine): NSLocaleUsesMetricSystem The key for the flag that indicates … Read more
You are missing dimensional analysis. For example (from the answer you linked to), in F# you can do this: let g = 9.8<m/s^2> and it will generate a new unit of acceleration, derived from meters and seconds (you can actually do the same thing in C++ using templates). In C#, it is possible to do … Read more

It uses pixels, but I’m sure you’re wondering how to use dips instead. The answer is in TypedValue.applyDimension(). Here’s an example of how to convert dips to px in code: // Converts 14 dip into its equivalent px Resources r = getResources(); int px = Math.round(TypedValue.applyDimension( TypedValue.COMPLEX_UNIT_DIP, 14,r.getDisplayMetrics()));
Traditionally by megabyte we mean your second option — 1 megabyte = 220 bytes. But it is not correct actually because mega means 1 000 000. There is a new standard name for 220 bytes, it is mebibyte (http://en.wikipedia.org/wiki/Mebibyte) and it gathers popularity.
TL;DR: use px. The Facts First, it’s extremely important to know that per spec, the CSS px unit does not equal one physical display pixel. This has always been true – even in the 1996 CSS 1 spec. CSS defines the reference pixel, which measures the size of a pixel on a 96 dpi display. … Read more
