A header-only type-safe zero overhead compile-time physical units C++17 library.
Zollstock is German for folding rule. It's a funny word, because it's a lie. Zoll means inch but the so called Zollstock normaly shows centimeters these days.
The library is still in a very early development stage. So please be careful when using it in production code. Currently there is support for length, time and angle units and combinations of them.
