When dealing with electrical systems, converting between Horsepower (HP) and kilovolt-amperes (kVA) is crucial for determining power capacity. This calculator simplifies the conversion between HP and kVA based on the power factor and voltage.
How to Use?
Choose the conversion type (HP to kVA or kVA to HP), then input the relevant values including power factor and voltage. Press 'Calculate' to get the result instantly. The conversion formulas are provided below for reference.
Conversion Formulas
HP to kVA Formula:
To convert HP to kVA, use the following formula:
kVA = (HP × 746) / (Voltage × Power Factor)
For example, to convert 10 HP at 230V and a power factor of 0.9, the kVA would be:
kVA = (10 × 746) / (230 × 0.9) = 3.6 kVA
kVA to HP Formula:
To convert kVA to HP, use the formula:
HP = (kVA × Voltage × Power Factor) / 746
For example, to convert 3.6 kVA at 230V with a power factor of 0.9, the horsepower would be:
HP = (3.6 × 230 × 0.9) / 746 = 10 HP
HP to kVA Conversion Table
| Horsepower (HP) | Voltage (V) | Power Factor (PF) | kVA |
|---|---|---|---|
| 5 HP | 230 V | 0.9 | 1.8 kVA |
| 10 HP | 230 V | 0.9 | 3.6 kVA |
| 20 HP | 230 V | 0.9 | 7.2 kVA |
| 50 HP | 230 V | 0.9 | 18.0 kVA |
Example Calculations
- 5 HP at 230 V with a power factor of 0.9: 1.8 kVA
- 10 HP at 230 V with a power factor of 0.9: 3.6 kVA
- 3.6 kVA at 230 V with a power factor of 0.9: 10 HP
FAQs
1. What is a power factor?
Power factor (PF) is the ratio of real power (measured in watts) to apparent power (measured in volt-amperes). It is a measure of how effectively electrical power is being used, and it ranges from 0 to 1.
2. Why is voltage important in the conversion?
Voltage is crucial because it directly impacts the relationship between HP and kVA. The higher the voltage, the lower the current needed for a given power output, and vice versa.
