Power Factor Calculator Online
1. kW (Kilowatts) Calculation
To calculate kW (real power), use the formula:
kW = kVA × Power Factor (pf)Where:
- kVA is the apparent power (in kilovolt-amperes)
- Power Factor (pf) is the ratio of real power to apparent power (a value between 0 and 1)
2. kVA (Kilovolt-Amperes) Calculation
To calculate kVA (apparent power), use the formula:
kVA = kW / Power Factor (pf)Where:
- kW is the real power (in kilowatts)
- Power Factor (pf) is the ratio of real power to apparent power (a value between 0 and 1)
3. Power Factor (pf) Calculation
To calculate the Power Factor (pf), use the formula:
Power Factor (pf) = kW / kVAWhere:
- kW is the real power (in kilowatts)
- kVA is the apparent power (in kilovolt-amperes)

Ohm’s Law (Voltage, Current, and Resistance)
The relationship between voltage, current, and resistance is given by:
V = I × RWhere:
- V is the voltage (Volts)
- I is the current (Amps)
- R is the resistance (Ohms)
Power Formula (Voltage, Current, and Power)
The relationship between power, voltage, and current is:
P = V × IWhere:
- P is the power (Watts)
- V is the voltage (Volts)
- I is the current (Amps)
Power with Resistance (Using Ohm’s Law)
The power can also be calculated using resistance:
P = I² × ROr:
P = V² / RWhere:
- P is the power (Watts)
- V is the voltage (Volts)
- I is the current (Amps)
- R is the resistance (Ohms)
