PhysicalConstants is a Julia package which has the values of a range of physical constants. Currently MKS and CGS units are supported.

Installation

The package can be installed directly from its github repository:

Pkg.clone("https://github.com/DataWookie/PhysicalConstants.jl")

Usage

Usage is pretty straightforward. Start off by loading the package.

julia> using PhysicalConstants

Now, for example, access Earth’s gravitational acceleration in MKS units.

julia> PhysicalConstants.MKS.GravAccel
9.80665

Or in CGS units.

julia> PhysicalConstants.CGS.GravAccel
980.665

Or, finally, in Imperial units.

julia> PhysicalConstants.Imperial.GravAccel
32.174049
