Can someone with a helmholtz calculation equation.

[Qaiphyx]

I want to find out how wide the port needs to be for specific frequencies. I suck with math. I have the volume, and the frequency, there will be no neck. Can someone break down the step of how to figure out the port. Also, what units are necessary? I want to just use cm, will that be fine if I just use cm for all the measurements?

The equation that I am using is here

You can plug in your values in the fields and the unknown will be calculated.
The acceptable units are given for each quantity.

I would like to caluclate it manually though. I don't want to use an online calculator. Already knew those existed.

So you want to solve the equation for A? And what do you mean by "there will be no neck"?
