Units.jl

Algebraically manipulate units and physical quantities in Julia. Units.jl uses the type system for logical unit system hierarchies, unit conversion, and flexible user-defined units. Future functionality aims to include mks and cgs units, constants, dimensional analysis, and electromagnetic units in different cgs sub-systems. I started this project to explore Julia. Other active projects that support unit analysis in Julia include Physical.jl and SIUnits.jl. The API is modelled after Python's Astropy units sub-module.

Installing

As this package is still in a state of active development, it is not currently available in the Julia package archive. To install and try it:

julia> Pkg.update()
julia> Pkg.clone("git://github.com/autocorr/Units.jl.git")
julia> import Units; u = Units;

Example Usage

Detailed documentation will be made available on the ReadTheDocs page once all core functionality has been implemented. Example usage of Units.jl includes:

julia> import Units; u = Units;
julia> c = 2 * u.meter^(1//2) / u.second
2 Meter^¹/₂ Second^-1
julia> c.<tab>
base dim   mag   ord   unit
julia> (c.base, q.unit)
(Length,Meter)
julia> c.dim
Dimension(d=1//2, m=0, t=-1,  i=0, θ=0, n=0, j=0)
