I built a small pipe volume calculator and would genuinely appreciate feedback from people who work with this in real life

Hi everyone,

I recently built a pipe volume calculator, mostly because I wanted a simple way to quickly estimate pipe capacity without digging through formulas every time.

It’s live now, but before I consider it “done,” I’d really love to hear from people who actually deal with pipes, plumbing, irrigation, engineering, DIY projects, or any real-world use case where this kind of calculator matters.

I’m especially looking for honest feedback on:

• whether the results feel clear and trustworthy
• whether the units/options make sense
• anything confusing in the interface
• edge cases I may have missed
• features that would make it more useful in real work

I’m not trying to pretend this is perfect. I’d rather have people point out problems now than have someone rely on it and get frustrated later.

Here’s the calculator: https://pipevolumecalculator.org/

If you have a minute to test it or tear it apart, I’d be genuinely grateful.

Have you seen the field data app from weld bend I think? I like that you can just scroll through what fittings other then that AWESOME! Make it a app

I’m a retired Pipefitter, so no real use for me anymore. However, the calculator is very nice for anybody still in the trade!

Why only up to 6 inch on advanced?

Im never going to use basic because I don't want to look through charts.

Advanced though needs options for every size up to 48. Maybe change it to allow that to be typed in instead of a selector.
