Start with the quantity you know
The focused calculators explain each rating basis in detail. Power factor affects the separate kW estimate from kVA, not the kVA-to-current relationship.
PRELIMINARY ENGINEERING TOOL
kW / kVA / amps calculator
Convert electrical load ratings with transparent assumptions and a substituted formula.
Inputs
Calculation steps
I = 10000.000 / (230.000 × 0.800)
Formula ID: POWER_SINGLE_PHASE_KW_V2
System voltage factor: 230.000
Assumptions and references
Preliminary calculation only. Verify inputs, manufacturer data, applicable standards, fault levels, and local requirements before construction or procurement.
UNDERSTAND THE TOOL
What this calculator does
Convert electrical power or apparent power into current using the selected system voltage, power factor and, when relevant, efficiency.
How to use it
- Choose the electrical system and known quantity.
- Enter the rating, voltage and realistic AC power factor.
- Identify mechanical output before applying efficiency.
- Review the substituted equation and limitations.
Fields and meanings
- Known quantity
- Choose kW, kVA, amperes or horsepower.
- Voltage
- Use the voltage applicable to the selected supply system.
- Power factor
- Required for AC active-power calculations.
- Efficiency
- Used only when mechanical output must be converted to electrical input.
Review required. Starting current, harmonics, duty cycle and diversity are outside this conversion.
