About Us

PowerToMassRatioCalculator.com was built to make power-to-mass (power-to-weight) math instant, accurate, and obvious for everyone — from vehicle enthusiasts to cyclists.

The calculator solves the simple relation ratio = power ÷ mass and stays unit-aware the whole time. Enter any two values (Power, Mass, Ratio) and the third is computed in real time. You can switch between watts (W) and horsepower (hp), kilograms (kg) and pounds (lbs), and view ratios as W/kg, W/lbs, hp/kg, or hp/lbs. Need cleaner outputs? Use the Decimals control. Handy actions like Copy summary, Reset, and Clear edits keep things fast.

What we care about

• Accuracy & clarity. Unit conversions are handled for you (e.g., hp ↔ W; kg ↔ lbs) so the math is transparent.
• Privacy by default. No accounts required; calculations happen in your browser.
• Speed & accessibility. A clean, mobile-friendly interface with sensible focus states and keyboard-friendly inputs.

Where this is going

• Saved scenarios and quick comparisons
• Export results to CSV/PDF
• More presets and unit quality-of-life options
• Shareable links for common setups
• Dark mode & tighter mobile ergonomics
