Gehtsoft.Measurements 1.1.14

About

The C# library to manipulate and convert with various measurements/units (e.g. distances, weight, angles, temperatures, and so on) expressed in various units (e.g. distances in inches, yards, meters).

The library may be useful for calculations, for example, in math, physic or GIS that does not depend from the system of units used (e.g. SI/Metric or Imperial) or to create a unit convertor application.

Currently, distance/length, velocity, weight, angular measurements, and energy units are supported.

The library is shared under LGPL license.

Using Library

The core class of the library is the generic structure Measurement. The structure accepts an enumeration as a parameter and this enumeration defines the measurement unit to be used:

 var v = new Measurement<DistanceUnit>(10, DistanceUnit.Feet);

or simply

 var v = DistanceUnit.Feet.New(10);

You can then manipulate this value using C# operator, format them or convert it into another unit:

 var v1 = v * 2;
 string v = v.ToString("N3");
 var v2 = v1.To(DistanceUnit.Meter);

or

    var x = (10.As(DistanceUnit.Yard) + 36.As(DistanceUnit.Inch)).To(DistanceUnit.Meter);

The class fully supports serialization using System.Text.Json and Binaron.Serializer (see https://github.com/zachsaw/Binaron.Serializer). XmlSerializer cannot be implemented for a readonly structures without introducing of non-safe code. Please refer to tests for an example how to implement an XML serialization in your code if needed (https://github.com/gehtsoft-usa/Gehtsoft.Measurements/blob/76fc639a657186dc91615839ca9ded4c14af7bc2/Gehtsoft.Measurements.Test/CoreClassesTest.cs#L181).

Defining your own units

You can define your own measurment units by creating a enumeration and mark it using Unit and Conversion attributes. The first attribute defines the unit name and the default accuracy of the values. The second attribute defines the rules of the conversion. One unit must always be a "base" unit, and conversion rules for other units defines how to convert the specified unit into a base unit.

enum MyWeightUnit
{
    //1 gram
    [Unit("g", 3)]
    [Conversion(ConversionOperation.Base)]
    Gram,

   //1 kilogram (1 kilogram = 1000 gram)
    [Unit("kg", 3)]
    [Conversion(ConversionOperation.Multiply, 1000)]
    Kilogram,
}
