Problem you'd like to fix

There presently exist several significant omissions in the list of constants provided in the calculator.

Describe the solution you'd like

A clear and concise description of what you want to happen.

All the constants provided by both other calculators should be considered for addition. The Stefan-Boltzmann is of particular interest to me at the moment.

Describe alternatives you've considered

Storing constants as variables does work to an extent, but it's cumbersome, especially when the calculator must be put into testing mode.

We are currently working on units algorithm, I'm linking this issue to our internal tickets. Thanks

That's good to hear! Also, I'm not sure if any have actually changed since they were added, but it wouldn't hurt to make sure that all the constants are up to date.
