Engineering Calculator

The mechanical calculations you need most on-site, in the workshop and at the design desk, all in one app. No spreadsheets, no catalogs, results in seconds.

POWER TRANSMISSION
• Belt & pulley: belt length, speed ratio, output speed, belt speed
• Conveyor: belt length and speed, reducer ratio for a target speed, belt load, motor power and drum torque
• Gear reducer: ratio, output speed and output torque
• Spur gear: center distance, gear ratio, output speed; undercut warning for low tooth counts
• Lead screw: thrust force, feed rate, motor torque; efficiency for trapezoidal screws

PNEUMATICS
• Cylinder push and pull force
• Standard bore size suggestion for a required force

MATERIAL & CUTTING
• Profile cutting optimization: cutting plan with minimum waste from your stock
• Profile order optimization: which stock lengths to buy and how many
• Send the cutting plan to the workshop as a PDF, or save it
• Material weight: steel, aluminum, nylon; plate, shaft, tube, box section

EASY TO USE
• Technical diagram with labeled dimensions for every calculation
• Your inputs are saved, so you can pick up where you left off
• Share results via WhatsApp, email and other apps
• Warnings for invalid or out-of-range values
• Light / dark theme, Turkish / English
• Works offline

New calculation tools are added regularly. We welcome your feedback and suggestions.
