Electrical unit conversion method
Power values are converted through watts, energy values through joules, and phase current uses the selected supply arrangement.
Pto = Pfrom × Kfrom / KtoEto = Efrom × Kfrom / KtoSingle-phase: I = P / (V × pf)Three-phase: I = P / (√3 × VLL × pf)where:
- K
- Unit-to-base conversion factor
- P
- Active power[W]
- E
- Energy[J]
- I
- Current[A]
- VLL
- Line-to-line voltage[V]
- pf
- Power factor
Power cannot be converted to energy without adding a duration.
How to use the Electrical Unit Converter
Choose Power, Energy, or Phase current. Power and Energy support conversion in either direction with category-specific units and a swap control; Phase current uses only the system, power, voltage, and power factor needed for the selected current formula.
- Choose Power, Energy, or Phase current.
- For a unit conversion, select two compatible units and type into either value field.
- Use the swap button to reverse the unit direction.
- For phase current, choose the supply system and enter active power, voltage, and AC power factor.
Calculation method and validation
The equations and symbol definitions above show the complete calculation basis. Inputs are checked before calculation so zero, negative, incompatible, or physically impossible combinations are flagged instead of silently producing a misleading result.
How to interpret the result
Use the main result as a starting value and read every supporting metric. Mechanical horsepower = 745.699872 W International Table BTU = 1055.05585262 J Three-phase voltage is line-to-line A passing or recommended result means the entered mathematical conditions are satisfied; it does not certify the complete installation or a particular product combination.
- Mechanical horsepower = 745.699872 W
- International Table BTU = 1055.05585262 J
- Three-phase voltage is line-to-line
Selection limits and next checks
Power and energy are different quantities and cannot be converted without a duration. Compare the output with the current applicable standard, local rules, exact VIOX product datasheet, environmental conditions, protection coordination, and the engineer's project requirements before procurement or installation.
