This calculator ensures you select the right equipment for efficient power management.

Formula for HP to kVA

The HP to kVA conversion is calculated using the formula:

kVA = (HP × 0.746) / (Efficiency × Power Factor)

Where:

• HP: Horsepower, a measure of mechanical power (1 HP = 0.746 kW).
• Efficiency: Motor efficiency as a decimal (e.g., 90% = 0.9).
• Power Factor (PF): Ratio of real power to apparent power (0 to 1, e.g., 0.8).
• 0.746: Conversion factor from horsepower to kilowatts.

For example, for 50 HP, 90% efficiency, and 0.8 power factor:

• kVA = (50 × 0.746) / (0.9 × 0.8) ≈ 51.81 kVA.

If efficiency is unknown, assume 100% (1.0) for simplicity.

How to Use Our HP to kVA Calculator

2. Enter Power Factor: Provide the power factor (e.g., 0.8).
3. Enter Efficiency (Optional): Input the motor efficiency as a percentage (e.g., 90%) or leave at 100%.
4. Calculate: Click to get the kVA value instantly.

Our intuitive calculator makes HP to kVA conversions quick and straightforward.

Example Calculation

Problem: Convert 100 HP to kVA with a power factor of 0.85 and efficiency of 92%.

Step-by-Step:

Formula: kVA = (HP × 0.746) / (Efficiency × Power Factor)

Input Values:

HP = 100

Efficiency = 92% = 0.92

Power Factor = 0.85

Calculate:

kVA = (100 × 0.746) / (0.92 × 0.85)

kVA = 74.6 / 0.782 ≈ 95.4

Result: The apparent power is approximately 95.4 kVA.
