The right-angle calculator built for the job site. RightAngle PRO handles the units you actually use — fractional inches (1/16, 1/32, 1/64), feet & inches, decimal inches, and millimeters — with instant diagram preview and high-precision results. Key Features Fractional Inches & Feet Support Choose your precision: 1/16", 1/32", or 1/64" — matched to your tape measure. Enter any fraction and the result automatically rounds to your selected precision. Sub-display instantly shows the converted value in your chosen second unit. Customizable Unit Combinations Mix and match unit displays freely in any combination. Real-Time Preview Every digit you type or delete is instantly reflected in the diagram. Input errors are immediately visible, making operation intuitive and efficient. Massive Calculation Range: Up to 500 km From small building components to wide-area surveying simulations — calculate angles to mountain peaks or tall structures while referencing a map. High Precision Display Side lengths displayed to 4 decimal places. Angles to 6 decimal places (4 in DMS). Tap any value for detailed precision readout. Left/Right Diagram Toggle Flip the diagram between right-rising and left-rising with one tap. PDF Export Save and print calculation results with diagrams as PDF. Easy to share on-site or by email. Light & Dark Mode Switch between Light and Dark mode to suit your environment and preference. Works Without Internet All calculations run offline. Calculation data is processed only on your device.
