Electrical Calculators

Choose an electrical calculator for your next step

Start with the quantity you know and the result you need. These routes connect unit conversion, current estimation and cable checks.

kW to horsepower — Compare power units and distinguish shaft output from electrical input.

CV to HP — Convert metric horsepower to mechanical horsepower.

kW to amps — Use electrical real power and circuit voltage.

kVA to amps — Use apparent power and the selected phase configuration.

Three-phase current — Check the line-to-line voltage and power basis.

Electrical wire size — Check conductor ampacity using the model’s installation inputs.

Voltage-drop calculators — Choose AWG/kcmil, conductor area or cable impedance inputs.

Read each calculator’s input definitions and limitations. A unit conversion or estimated operating current is one step in a larger equipment or installation assessment.
