Volts to Horsepower Calculator

Formula

The formula to calculate the Horsepower (HP) from volts is:

\[ \text{HP} = \left(\text{V} \times \text{I} \times \text{E} \times \text{PF}\right) / 746 \]

Where:

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

Volts to Horsepower Definition

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.

Example Calculation

Let's assume the following values:

Voltage supply (V) = 230 volts
Current (I) = 10 amperes
Efficiency of the motor (E) = 0.85
Power factor (PF) = 0.9

Using the formula:

\[ \text{HP} = \left(230 \times 10 \times 0.85 \times 0.9\right) / 746 = 2.35 \text{ HP} \]

The Horsepower (HP) is 2.35 HP.
