Convert between Watts, Horsepower, Kilowatts, and BTU instantly.
In the world of physics and engineering, power is the rate at which work is performed or energy is transferred. Whether you are a solar technician in Karachi calculating panel output, an automotive engineer in Detroit measuring engine horsepower, or a homeowner in London comparing air conditioner wattage, a Power Converter is an essential technical utility. Power units vary significantly across industries and regions, making accurate conversion vital for safety and efficiency.
Our online unit solver provides instant transitions between various measurements of energy flow. By utilizing our wattage analysis utility, you can convert between Watts, Kilowatts, Horsepower, and even British Thermal Units (BTU). This tool ensures that your calculations remain precise, helping you design better electrical systems and understand the energy consumption of your appliances.
To provide a high-level scientific analysis, our energy estimator categorizes power measurements into several key systems:
The Watt (W) is the SI unit of power. It is used globally for everything from light bulbs to massive power plants. 1,000 Watts equal 1 Kilowatt (kW), which is the standard unit for billing household electricity.
Commonly used in the automotive and industrial sectors to describe the output of engines and electric motors. Our Power Conversion Utility supports both Imperial and Metric horsepower variants.
Crucial for the HVAC (Heating, Ventilation, and Air Conditioning) industry. If you are calculating the cooling capacity of an AC unit, you will often need to convert Watts into BTU per hour.

$Watts (W) to Horsepower (hp) = \frac{W}{745.7}$
$Kilowatts (kW) to BTU/hr = kW \times 3412.14$
Our tool handles these complex multipliers automatically, providing results up to 6 decimal places.
