Free online tool for instant bidirectional conversion between watts and horsepower. Perfect for engineers, mechanics, and DIY enthusiasts.
Our Watts to HP Converter is a free online tool designed for instant conversion between two fundamental units of power: watts (W) and horsepower (HP). This bidirectional converter provides real-time results as you type, making it perfect for engineers, mechanics, electricians, and DIY enthusiasts.
Key features: Real-time conversion, bidirectional calculation (watts to HP and HP to watts), responsive design that works on all devices, and a clean, intuitive interface with a futuristic aesthetic.
Understanding power conversions is essential in many fields. Watts are the SI unit of power used globally in scientific contexts, while horsepower remains popular in automotive, mechanical engineering, and industrial applications. With our converter, you can seamlessly switch between these units for accurate calculations.
Watts to HP: HP = Watts × 0.00134102
HP to Watts: Watts = HP × 745.7

Watts (W) are the SI unit of power, defined as one joule per second. Horsepower (HP) is an imperial unit of power originally developed to compare the output of steam engines with the power of draft horses. One mechanical horsepower is approximately equal to 745.7 watts.
Our converter uses the standard conversion factor of 1 HP = 745.699872 watts (mechanical horsepower). This provides industry-standard accuracy suitable for most engineering, automotive, and industrial applications. Results are displayed with up to 6 decimal places for precision.
Yes, mechanical horsepower (used in the US and UK) is approximately 745.7 watts, while metric horsepower (used in Europe) is approximately 735.5 watts. Our converter uses mechanical horsepower by default, but you can select metric in advanced options if needed.
Absolutely! Our Watts to HP Converter is fully responsive and works perfectly on all devices including smartphones, tablets, laptops, and desktop computers. The interface is touch-friendly with appropriately sized buttons and inputs.
No installation is required. This is a completely web-based tool that runs directly in your browser. There are no downloads, installations, or registrations needed - just visit the page and start converting.
