eng-units

Rust library to build, calculate and convert custom engineering units.

Example Usage

Creating an engineering unit

rust let unit = EngUnit::from_unit(Unit::Meter, 1.0); println!({unit}); 1 m

Changing unit type

rust let unit = EngUnit::from_unit(Unit::Meter, 1.0); unit.change_unit(Unit::Millimeter); println!({unit}); 1000 mm

Printing an engineering unit

rust println!({unit}); 1000 mm

Addition

Scalar Addition

rust let unit = EngUnit::from_unit(Unit::Meter, 1.0); let unit_2 = unit + 2; println!({unit_2}); 3 m

Unit Addition

rust let unit_1 = EngUnit::from_unit(Unit::Meter, 100.0); let unit_2 = EngUnit::from_unit(Unit::Kilometer, 1.0); let unit_3 = unit_2 + unit_1; println!({unit_3}); 1.1 km

Multiplication

Scalar Multiplication

rust let unit_1 = EngUnit::from_unit(Unit::Millimeter, 1000.0); let unit_2 = 2 * unit; println!({unit_2}); 2000 mm

Unit Multiplication

rust let unit_1 = EngUnit::from_unit(Unit::Meter, 100.0); let unit_2 = EngUnit::from_unit(Unit::Centimeter, 500.0); let unit_3 = unit_1 * unit_2; println!({unit_3}); 500 m^2
