       Show HN: I created Units Converter that contains 5000 units across
       78 categories
        
       I have been working on my project for the last one year and
       developed around 600+ tools. The units converter covers almost
       every possible unit and I am planning to add more to it.

       | Everything else I've found have been just super fiddly.

       | I wanted to put in a plug for my employer's open-sourced C++
       | units framework, called Au: https://github.com/aurora-
       | opensource/au
       | 
       | The library incorporates dimensional units into the C++ type
       | system with an emphasis on correctness (including considerations
       | for overflow, rounding, loss of precision, etc) and minimal
       | runtime overhead.
       | 
       | As a very simple example of what using this library could look
       | like, here is a tiny code snippet taken from one of the
       | tutorials:                 constexpr double speed_mph = 65.0;
       | constexpr double speed_mps = (miles / hour)(speed_mph).in(meters
       | / second);
       | 
       | In a larger program, of course, the whole point is to avoid using
       | naked "doubles" (or floats or ints, etc) at all, and instead use
       | the library's "Quantity" types, which encode information about
       | their units. Conversions are done automatically, and incompatible
       | operations become compile-time errors.                 const auto
       | time = hours(1.0)       const auto distance = miles(65.0)
       | const auto average_speed = distance/time;
       | 
       | The tutorials are a nice way to be introduced to the library:
       | https://aurora-opensource.github.io/au/tutorial/
       | 
       | From a user's point of view (I am a physicist by training), I
       | find the library wonderfully unobtrusive and "natural" to use.

               | For people who cook in the US, a set of "measuring
               | spoons" is a very common kitchen tool.
               | 
               | "Teaspoon" and "Tablespoon" are units of measurement of
               | volume, not bits of silverware. "Tea spoon" and "Table
               | spoon" or "Soup spoon" are pieces of silverware, not
               | units of measure!
