Mechtics Toolkit

Mechtics Toolkit is a practical mechanical engineering tools and calculator app designed for engineers, technicians, fitters, mechanics, students, and workshop professionals.

The app brings together useful mechanical calculators in one simple offline toolkit, helping you perform quick engineering calculations, unit conversions, and preliminary design checks wherever you are.

Key features include:

• Bolt Torque Calculator
Estimate bolt tightening torque using clamp force, bolt diameter, and nut factor.

• Pipe Flow Calculator
Calculate flow velocity, Reynolds number, friction factor, pressure drop, and head loss for incompressible liquid flow in circular pipes.

• Bearing Life Calculator
Estimate basic L10 bearing life for ball and roller bearings using dynamic load rating, equivalent load, and speed.

• Unit Converter
Convert commonly used mechanical and engineering units including length, force, torque, pressure, flow rate, velocity, power, energy, temperature, density, and viscosity.

• Calculation History
Save and review previous calculations for quick reference.

• Formula Notes and Assumptions
View formulas, units, assumptions, and warnings for each calculator.

Mechtics Toolkit is built for quick, clear, and convenient mechanical calculations. It is useful for workshop checks, study, maintenance planning, field work, and preliminary engineering estimates.

Important disclaimer:
All calculations are intended for reference and preliminary use only. Results must be verified by a qualified engineer before being used for safety-critical, load-bearing, pressure, rotating equipment, or production applications. Actual engineering performance may vary depending on material properties, friction, lubrication, installation condition, manufacturing tolerances, operating environment, and applicable standards.
