MultiCalculators - 110+ free engineering calculators
by•
I created MultiCalculators to make engineering calculations easy for students, professionals, and hobbyists.
You’ll find 110+ tools covering:
Mechanical (torque, force, springs, machining...)
Electrical (kW-kVA, power factor, voltage drop...)
Civil (beam, column, stress-strain...)
HVAC
Coding & electronics
Unit converters
All calculators are free, clean UI, fast loading, and ad-free.
