Cross sectional area gives wrong conversion

Hi, app works well and is easy to use and smooth but the calculation for circular to rectangular duct is wrong. If I put 400 diameter in circular, it returnees 400x400 duct equivalent. I’m sure you can see this is not correct. This brings the other calculations in doubt too unfortunately

Why is it only metric!?!?!

The app seems to work well but in the U.S. we use standard measurements not metric. I'm not sure why the app was designed without an option to switch!
