Atmoos Quantities

This library enables type-safe handling of quantities. It is a general purpose library that allows third parties to define their own units if needed. Many units are predefined in this library or are available on nuget here.

It is based on the international system of units (SI), but also supports many other units, such as imperial units.

Design principles:

  • Type-safe by default.
  • General purpose, i.e. extendable.
    • Broad set of units available in Atmoos.Quantities.Units.
    • Custom units are supported, too.
    • All metric and binary prefixes are supported.
  • Serialization is supported via Atmoos.Quantities.Serialization
  • Optimized for
    • accuracy: numerically more stable than just using doubles.
    • low memory footprint: all quantities are structs and don't allocate on the heap.
    • speed: likely faster than naive implementations.

Usage Patterns

Add this global using somewhere in your project.

global using static Quantities.Systems;

Then, quantities can be used like this:

Time hours = Time.Of(4, Metric<Hour>());
Length feet = Length.Of(2, Imperial<Foot>());
Volume volume = Volume.Of(3, Cubic(Si<Metre>()));
Length kilometres = Length.Of(16, Si<Kilo, Metre>());
Velocity kilometresPerHour = Velocity.Of(4, Si<Kilo, Metre>().Per(Metric<Hour>()));
Velocity arithmeticVelocity = kilometres / hours; // 4 km/h
Area area = volume / feet; // 4.921... m²

Supported Si Prefixes

They are all compatible with each other.

Supported Quantities

The currently supported quantities are:

├── Area
├── Data
├── DataRate
├── ElectricCurrent
├── ElectricPotential
├── ElectricalResistance
