Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Engineering
Transformer Losses Calculator
Calculate the operating efficiency of a power transformer at any load factor, accounting for both iron (no-load) and copper (load-dependent) losses. Use this to compare transformer performance and estimate energy costs.

Engineering
Power Transmission Calculator
Converts torque (N·m) and rotational speed (rpm) into mechanical power in kilowatts. Use it when sizing motors, drives, or shafts, or when checking whether a drivetrain can handle a given load without overheating.
