Fluid R717 = new Fluid(FluidList.Ammonia);
R717.UpdatePT(Pressure.FromBars(10), Temperature.FromDegreesCelsius(100));

Console.WriteLine(R717.Density); // 5.751 kg/m³
Console.WriteLine(R717.DynamicViscosity); // 1.286e-05 Pa·s

What is unit-safety?

"As long as you do all your calculation in SI-units.." is the normal saying but if you have tried spending days debugging code to figure out you 'just' had a wrong unit - then unit-safety is your new friend

This is an example of a common unit mistake - With unit-safety you get an error where you did the mistake.

Mass mass = new Mass(10, MassUnit.Kilogram);
Volume volume = new Volume(4, VolumeUnit.CubicMeter);

Density D1 = mass / volume; // 2.5 kg/m³
Density D2 = volume / mass; // WrongUnitException: 'This is NOT a [kg/m³] as expected! Your Unit is a [m³/kg]'

Converting between units is not your headache anymore

You just input the units you have and ask for the units you want:

Length length = new Length(5.485, LengthUnit.Inch);
Length height = new Length(12.4, LengthUnit.Centimeter);

Area area = length * height; // 0.01728 m²
Console.WriteLine(area.ToUnit(AreaUnit.SquareFoot)); // 0.186 ft²
Console.WriteLine(area.ToUnit(AreaUnit.SquareCentimeter)); // 172.8 cm²
