Calculator from Hp to kVA can be somewhat overwhelming, however with this tool you could convert with just 1 click.

You will have the step-by-step explanation of how the conversion is done and what is the formula used for the calculation.

With the idea of making things even easier, we present some illustrative examples, equivalence tables from Hp to kVA and common values for the efficiency and power factor of electric motors.

## ⚡HP formula to kVA

The HP to kVA formula is applied to electric motors that can be single-phase, two-phase or three-phase, the difference of this formula with that of HP at kW is that it includes the power factor .

**Where:**

**S (kVA) = Kilovolt-Amps.**It is the apparent power we wish to find.**HP (Horsepower) =**Horsepower, data that you can see on the nameplate of the electric motors or by doing a search of the engine reference on the internet.**E = Efficiency of the electric motor.**Efficiency is the ratio between the mechanical power delivered by the motor (output) and the electrical power supplied to the motor (input). Efficiency = (Mechanical power output / Electric power input) x 100% Therefore, a motor that It is efficient at 85% converting 85% percent of the electrical energy input into mechanical energy, the remaining 15% of the electrical energy dissipates as heat, evidenced by an increase in the engine temperature. Some reference values for motor efficiency can be found in countless internet tables.**FP = Power factor.**The power factor is an expression of energy efficiency. It is usually expressed as an integer from 0 to 1, and the lower the value, the less efficient is the use of energy. It is a value of each team and can be obtained from the characteristics of the same or from the catalogs.

## ⭐**How to convert Hp to kVA in only 3 step**

### Step 1 (Multiply Hp x 0.746)

Multiply Hp (Horsepower) by 0.746. Example, if you have 100Hp (horsepower) multiply by 0.746 and get 74.6. (100 × 0.746 = 74.6).

### Step 2 (Efficiency x FP)

Multiply the power factor by the efficiency of the engine. For example, if the engine has an efficiency of 80% and the power factor is 0.9, you must Multiply 0.8 (80%) by 0.9 to get 0.72. (0.8 × 0.9 = 0.72).

### Step 3 (Divide step 1 and 2)

Divide step 1 by step 2. Example, ((100 × 0.746) / (0.9 × 0.8) = 103.61).

## ✍Examples of conversions from Hp to kVA

### Example No. 1 (Rock Crusher)

A rock crusher has a power of 40Hp, a power factor of 0.86 and an efficiency of 89%, how many kVA does the rock crusher have?

Rta: // The first step is to multiply 40 × 0.746, which will result in 29.84, then this result should be divided between the multiplication of the Power Factor and efficiency, as follows: 40 × 0.746 / (0.86 × 89 %) = 38.99kVA

### Example No. 2 (Steel bender)

A steel bending machine has a power of 20Hp, with a power factor of 0.82 and an efficiency of 84%, how many kVA will the steel bender have?

Rta: // Hp must be multiplied by 0.746, resulting in 14.92, then the power factor must be multiplied by efficiency (this value must be in decimals and not as a percentage, to pass it simply divide 84% by 100, which gives as a result 0.84), continuing with the operation the result will be: 0.688, then you must divide the first result by the second, as follows: 14.92 / 0.68 = 21.15kVA.

### Example No. 3 (Electric Curtain)

An engine for an electric curtain has a power of 7.4Hp, a power factor of 0.88 and an efficiency of 90%, how many kVA does the curtain motor have?

Rta: // It’s simple, you just have to enter the previous parameters to the calculator shown in this article and you give it to calculate, the result will be 6.97kVA.

## ☝Difference and explanation of Hp and kVA

Horsepower is a unit of mechanical power, while kVA (kilovolt-amps) is a unit used to classify electrical power.

In electrical terms, 1 horsepower equals 746 watts, but the conversion of Hp to kVA also requires knowing the power factor of the electrical device and efficiency.

An industry standard average rating of 0.8 power factor (for motors) or 0.9 for other electrical devices can be used if the actual power factor is unknown, as long as efficiency can be used 80 %. The use of the power factor and efficiency in conjunction with the known Hp will give a rough but reliable understanding of the power equivalence in kVA.
