Free Power Converter - Watts, Kilowatts, Horsepower, BTU Online

A 1 mechanical horsepower (hp) = 0.746 kW. 1 metric horsepower (PS) = 0.7355 kW. Car specs usually use metric PS. Quick rule: 1 hp is about 3/4 kW.

A Power (watts) is the rate of energy use at any instant. Energy (kWh) is total energy consumed over time. Energy = Power x Time. A 1,000 W device running 1 hour = 1 kWh.

A BTU (British Thermal Unit) per hour is a power unit common in the US for HVAC. 1 BTU/h = 0.293 W. A 12,000 BTU/h AC unit = about 3,517 W.

A Average US home uses about 1.2 kW continuously (about 30 kWh/day). Peak usage with AC, oven, dryer running can reach 10-15 kW.

A hp (mechanical horsepower) = 745.7 W, originated in Britain. PS (Pferdestaerke, metric horsepower) = 735.5 W, used in Europe and Japan. The difference is about 1.4%.

A kcal/h is a unit of thermal power, often used to express heat transfer rates, especially in biology, nutrition, and some industrial processes. Converting kcal/h to watts or BTU/h helps understand and compare energy transfer in different contexts, like comparing metabolic rates or heat output of equipment, ensuring consistent power measurements across various systems.

A For small electronic devices like phone chargers or LED lights, watts (W) are suitable. Home appliances such as ovens or air conditioners are typically measured in kilowatts (kW). When dealing with large industrial equipment, engines, or vehicles, horsepower (hp) is often used for mechanical power. For massive energy generation, like power plants, megawatts (MW) are the standard. This tool helps you convert and compare power across all these scales.

A This power converter focuses on 'real power' units like watts, kilowatts, and horsepower, which represent the actual power used or produced. VA (Volt-Amperes) and kVA (kiloVolt-Amperes) measure 'apparent power,' which includes both real and reactive power. While related in electrical systems, real and apparent power are distinct. Our tool provides precise conversions for direct power quantities, making it ideal for comparing active mechanical, thermal, or electrical power.

A To compare a gasoline engine's horsepower (hp) with an electric motor's kilowatt (kW) output, use a power converter. Gasoline engines are typically rated in hp, while electric motors often use kW. This tool allows instant conversion between these units, enabling you to directly evaluate and compare their power capabilities for various applications, such as vehicle performance, industrial machinery, or even electric vehicle specifications.

A Use the Power Converter to easily switch between BTU/h and kilowatts. Enter your appliance's BTU/h rating, and the tool instantly provides the equivalent in kW. This is crucial for understanding an appliance's power consumption in regions that primarily use the metric system (kW) and ensuring compatibility with local electrical grids and calculating energy costs effectively.
