Calculate using house width, length, and pitch. Convert measurements between imperial and metric units in real time. Determine from width and length in meters, centimeters, yards, feet, or inches. Convert pitch to degrees or radians.
Convert vibration units including velocity, acceleration, and displacement. Switch between Hz and CPM for frequency. Convert displacement between mils and microns with options for RMS, 0-peak, and peak-peak.
Calculate casing sizes, weights, and hydrostatic pressure with unit conversions between imperial and metric systems. Switch units instantly. Perform pressure calculations for oil and gas applications. Access accurate data for field and office use.
Create and submit solar surveys for residential projects. Upload site details, capture images, and generate reports. Share surveys with team members and track project status in real time.
Calculate cylinder force and pressure automatically
Allows users to input values for cylinder calculations, power, pressure difference, piston diameter, speed, lifting time, and volume flow. The automatically computes results without requiring manual formulas.
Calculate metrics such as area, volume, force, velocity, and time. Input piston diameter, pressure, and oil flow to get results for both piston and rod sides. Perform real-time calculations for extraction and retraction forces.
Calculate kinematic movements with step-by-step structuring. Input parameters for constant velocity or accelerated motion. Solve linear or rotational movements with minimal data. Support multiple units and variations.
The app offers unit conversions for acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. All conversions are performed on a single screen.
Calculates balanced and competitive car tunes without manual adjustments. It supports all vehicles in Forza Motorsport 7. Users can select general or track-specific tunes. Options include night and rain settings.
The app provides HVACR service technicians with refrigerant data for system diagnostics. It calculates pressure and temperature, and can determine superheat and subcooling for system charging and troubleshooting.
