How to use the well-known physical constants?

[eigenein]

👋 uom seems to have defined a bunch of the well-known constants, such as speed_of_light_in_vacuum or planck_constant.

But I fail to understand how to use them: they don't implement Quantity, but instead, they implement Conversion. Am I supposed to write something like Velocity::new::<speed_of_light_in_vacuum>(1.0) every time I need a constant? Or do I overlook something?

Your links to the speed of light and the planck constant are for a context where these are used as units. e.g. 1.0 speed of light in a vacuum as a unit of velocity is an equivalent way of writing 299_792_458.0 meters per second.

#32 exists to add universal constants to uom. As a work-around you can manually define them in your code: #26 (comment). This also applies for anyone coming to this discussion wondering how to write their own constants.
