About Us

Rectangular to Polar Coordinates is a tiny tool with a big goal: make coordinate conversions instant, accurate, and obvious—on desktop or phone. It’s built with ❤️ by BigTechies.

What it does (and why)

Students, engineers, and makers often bounce between rectangular (x, y) and polar (r, θ). Our calculator removes friction with:

• Quadrant-aware angles via atan2(y, x) so θ lands where you expect
• Angle toggle for Degrees ↔ Radians
• Adjustable precision and normalized θ for consistent presentation
• Bidirectional conversion: Rectangular → Polar and Polar → Rectangular
• Copy/Clear controls and quick actions for rapid iteration

How it works

Under the hood we use standard trig: r = √(x² + y²), θ = atan2(y, x), and for the reverse, x = r·cos(θ), y = r·sin(θ). We display r ≥ 0 and normalize θ for clarity.

Roadmap

• Batch mode (paste a list of points; export results to CSV)
• Complex-number mode for phasors (a + bi ↔ r∠θ)
• Shareable links and small graph preview
• Keyboard-first shortcuts and enhanced accessibility
• Dark mode and improved mobile ergonomics

Our principles

• Accuracy first. The math should be correct and transparent.
• Privacy by default. No accounts required; minimal data practices.
• Speed & clarity. Crisp UI, fast feedback, readable on any screen.
• Accessibility. Keyboard-friendly inputs and sensible focus states.
