Enter the voltage supply, current, efficiency of the motor, and power factor into the calculator to determine the horsepower.

## Volts To Horsepower Formula

The following formula is used to calculate the horsepower from volts.

HP = (V * I * E * PF) / 746

Variables:

- HP is the power output (horsepower)
- V is the voltage supply (volts)
- I is the current (amperes)
- E is the efficiency of the motor (decimal)
- PF is the power factor (decimal)

To calculate the horsepower, multiply the voltage supply by the current, then multiply the result by the efficiency of the motor and the power factor. Divide the result by 746 (since one horsepower is equivalent to approximately 746 watts).

## What is Volts To Horsepower?

Volts to horsepower is a conversion that determines the power output (horsepower) of an electrical motor using its voltage supply. This conversion is important in electrical engineering and automotive industries to understand the performance of motors or engines. The conversion typically involves other factors such as efficiency and power factor, and is based on the principle that electrical power (measured in watts) is the product of voltage (volts) and current (amperes). One horsepower is equivalent to approximately 746 watts.

## How to Calculate Volts To Horsepower?

The following steps outline how to calculate the Volts To Horsepower using the given formula:

- First, determine the voltage supply (V) in volts.
- Next, determine the current (I) in amperes.
- Next, determine the efficiency of the motor (E) as a decimal.
- Next, determine the power factor (PF) as a decimal.
- Use the formula: HP = (V * I * E * PF) / 746 to calculate the power output (HP) in horsepower.
- Finally, calculate the Volts To Horsepower.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge:

voltage supply (V) = 120 volts

current (I) = 10 amperes

efficiency of the motor (E) = 0.85

power factor (PF) = 0.9
