How to Convert kW to HP to kVA
Follow these formulas for accurate conversion:
Step 1: Convert kW to HP
Formula:
Example: If kW = 10, then HP = 10 × 1.341 = 13.41 HP.
Step 2: Convert kW to kVA
Formula:
Example: If kW = 10 and Power Factor = 0.8, then kVA = 10 ÷ 0.8 = 12.5 kVA.
Complete Example
Given: Power = 10 kW, Power Factor = 0.8
Results: HP = 13.41 HP, kVA = 12.5 kVA

FAQs – KW to HP to KVA Calculator
Multiply kilowatts by 1.341. This gives mechanical horsepower.
Divide kW by the power factor. Example: kVA = kW ÷ PF.
Most electrical systems use 0.8 to 0.9. Motors often use 0.8.
kVA shows apparent power. It helps size generators and transformers correctly.
Yes. It works well for motor power, generator sizing, and load estimation.
Yes. 1 kW equals 1.341 HP, so HP values are always higher.
No. Power factor only affects kVA, not horsepower.
