Under the Hood: Building a Zero-Backend, Ultra-Fast Construction Calculator Suite

The UI Challenge: Smooth User Experience

Because construction projects use different systems depending on where you live, the inputs must seamlessly support both Imperial (inches/feet/yards) and Metric (cm/meters) units.

I built a custom React hook useUnitConverter to dynamically convert inputs under the hood while preserving the user's preferred viewing units. All calculations run on a debounced state to ensure that typing isn't interrupted by heavy UI re-renders.

Check it out live at constructmath.com. I'd love to hear your feedback on the UI and code structure! How do you handle complex client-side calculations in your own projects?
