Formula (extracted LaTeX)

\[1 \text{ hp} = 745.69987158227 \text{ W}\]

1 \text{ hp} = 745.69987158227 \text{ W}

Formula (extracted LaTeX)

\[1 \text{ hp} \approx 0.7457 \text{ kW}\]

1 \text{ hp} \approx 0.7457 \text{ kW}

Formula (extracted LaTeX)

\[\text{kW} = \text{hp} \times 0.7457\]

\text{kW} = \text{hp} \times 0.7457

Formula (extracted LaTeX)

\[1 \text{ hp (electric)} = 746 \text{ W}\]

1 \text{ hp (electric)} = 746 \text{ W}

Formula (extracted LaTeX)

\[1 \text{ hp (electric)} = 0.746 \text{ kW}\]

1 \text{ hp (electric)} = 0.746 \text{ kW}

Formula (extracted text)

$1 \text{ hp} = 745.69987158227 \text{ W}$ $1 \text{ hp} \approx 0.7457 \text{ kW}$ $\text{kW} = \text{hp} \times 0.7457$

Formula (extracted text)

$1 \text{ hp (electric)} = 746 \text{ W}$ $1 \text{ hp (electric)} = 0.746 \text{ kW}$ $\text{kW} = \text{hp} \times 0.746$

Formula (extracted text)

$1 \text{ PS} = 735.49875 \text{ W}$ $1 \text{ PS} \approx 0.7355 \text{ kW}$ $\text{kW} = \text{PS} \times 0.7355$
