DoenaSoft.UnitsOfMeasurement 1.3.0

This package allows the conversion of common SI and American units within the same category (area, energy, length, temperature, time, volume, weight/mass)

All units can be accessed by type name (e.g. Meter) or serializable / SI value (e.g. "m");

Sample conversion from Kilogram to pound:

var lb = new Value<Pound>(1);

var kg = ValueConverter.Convert<Kilogram>(lb).Round(9);

Assert.AreEqual(0.45359237, kg.Scalar);

kg = new Value<Kilogram>(1);

lb = ValueConverter.Convert<Pound>(kg).Round(9);

Assert.AreEqual(2.204622622, lb.Scalar);

It also allows the registration of custom units (i.e not pre-defined in this assembly) with a conversion factor to the category's base unit.

var custom = new CustomWeight(0.0311034768, "oz.tr."); // ounce

UnitConverter.RegisterCustomUnit(custom);

var result = UnitConverter.ToUnitOfMeasurement("oz.tr.");

It also alows the creation of fractional units such as meters per second

var mps = UnitConverter.ToUnitOfMeasurement("m/s");

You can also add values from the same unit category to each other without converting the units first:

var source = new Value<FractionUnit<Meter, Second>>(30);

var target = source.Add(new Value<FractionUnit<Mile, Hour>>(15));

Or calculate Superman's height in meters:

var sourceFeet = (new Value<Foot>(6m)).Add(new Value<Inch>(4m)); // 6'4"

var targetMeter = ValueConverter.Convert<Meter>(sourceFeet).Round(2); // 1.93m

You can also convert between volume and weight units with a given density.

const double DensityOfHelium = 0.1785; // kg/l

var source = new Value(5, UnitConverter.ToUnitOfMeasurement("dm3"));

var target = ValueConverter.Convert(source, new Kilogram(), new DensityValue<Density<Kilogram, Liter>>(DensityOfHelium));

You can even convert values with fractional units where the unit categories are inverted, such as liter per 100 km (volume/length) to gasmileage (length/volume)

const double LitersPer100km = 5.9 / 100;

var source = new Value<FractionUnit<Liter, Kilometer>>(LitersPer100km);

var target = ValueConverter.Convert(source, new FractionUnit<Mile, USLiquidGallon>()).Round(5); // 39.86688 miles per gallon
