How to Use a Volts to kW Calculator
Follow these simple steps to use the volts to kW calculator correctly:
Step-by-Step Instructions
- Enter the voltage (V) value: Example: 220V
- Enter the current (Amps or A): Example: 10A
- Select the system type: Choose between DC, Single-phase AC, or Three-phase AC.
- Enter power factor (for AC only): Typical values range from 0.8 to 1.
- Click the "Calculate" button.
- View the result in kilowatts (kW).
Tip: Always double-check your input values to ensure accurate results.
How to Convert Volts to kW (Step-by-Step)
To convert volts to kilowatts, you must also know current and system type.
Basic Formulas
For DC:Real-Life Example
Example: Convert 220V and 10A into kW (single-phase AC, PF = 0.9)
1. Identify values: Volts = 220V, Current = 10A, Power Factor = 0.9
2. Apply formula: kW = (220 × 10 × 0.9) ÷ 1000
3. Calculate: kW = 1980 ÷ 1000
4. Final result: kW = 1.98 kW
Result: 220 volts and 10 amps equal 1.98 kilowatts.

Assumption: Current = 10 Amps
| Voltage (V) | Current (A) | Power (kW) |
|---|---|---|
| 110 V | 10 A | 1.10 kW |
| 120 V | 10 A | 1.20 kW |
| 220 V | 10 A | 2.20 kW |
| 230 V | 10 A | 2.30 kW |
| 240 V | 10 A | 2.40 kW |
| 380 V | 10 A | 3.80 kW |
| 400 V | 10 A | 4.00 kW |
| 415 V | 10 A | 4.15 kW |
Note: Values may change depending on power factor and system type.
Frequently Asked Questions
No. You need current (amps) and sometimes power factor to calculate kW.
