Engineering students and professionals deal with repetitive calculations every day — torque, voltage drop, stress, power factor, machining…
So I created MultiCalculators, a collection of 110+ free engineering calculators with a clean UI and fast performance.
These calculators cover:
Mechanical (Torque, Springs, Machining, Stress…)
Electrical (kW–kVA, Voltage Drop, Power Factor, Wire Gauge…)
Civil & Structural (Beam Deflection, Column Buckling, MOI…)
HVAC

Electronics
Physics & Maths
Unit converters
Every calculator includes formulas, diagrams (where needed), and explanations.

Conclusion:
If this helps even one student or engineer save time or better understand formulas, it’s worth it.
Suggestions for new tools are always welcome.
