Visionary Software Solutions Measurement API: fluent, joyful measurement...FOR SCIENCE! #
Meant to fight the odious practice witnessed in many code bases of using
only integers/doubles for measurements/units and "knowing contextually"
that a number corresponds to a measurement in celsius...
(which may be converted in the body of a method).
The goal of this API is to enable code written about measurements to be
clear, expressive, and straightforward to reason about and understand by
baking behaviors (such as well known conversion factors and arithmetic)
directly into types.
Features #

Builds on me_sure_meant, providing support for Temperature.
Common SI and Imperial/US Customary units.
Fluent definition, unit conversion, and addition/subtraction.
Uncertainty in measurement with propagation through calculations.
Framework pieces to easily extend and evolve, replacing implementations or adding new features
Full SI prefix support for all your yottakelvin and quectokelvin needs
Extension Methods to make defining a quantity as easy as writing (10.kelvin() + 42.fahrenheit() + Kelvins(crude(10), Kelvin.megakelvin) - 30000.celsius()).toUnit(Fahrenheit());

First Class (No, really, they're dedicated classes!) support for Temperature measurements: #
- SI: `Kelvins`, `DegreesCelsius`
- Imperial: `DegreesFahrenheit`

Also note that the package is built using Best Practice software engineering principles.
The code is meant to be as SOLID as possible (thanks Uncle Bob!) with Stable Abstractions that
work interchangeably (don't like Crude or BasicUncertainty Measurements? Roll your own!).
DECORATOR for SI MetricPrefix was an obviously nice win I'm surprised I haven't seen done more.
The library has test coverage and planned seams for modularization once the basics are proven out.
Getting started #
Dependency: me_sure_meant library.
This package is "platform"/foundational. It should work in any Dart 3+ runtime environment.
Usage #
Check out the demos in example/temper_example.dart
Here's a teaser #
final mess = (10.kelvin() + 42.fahrenheit() + Kelvins(crude(10), Kelvin.megakelvin) - 30000.celsius()).toUnit(Fahrenheit());
print(mess);
assert(mess == 17945568.33.fahrenheit());
