    What is Power Converter?

    The Power Converter is a free online tool that helps you convert values between different units of power. Convert between watts, kilowatts, megawatts, horsepower, BTU/h, ft·lb/s, cal/s, and kcal/s. This tool provides instant, accurate results with support for all major unit conversions in this category.

    How the Conversion Works

    Power units convert through watts. 1 kW = 1000 W, 1 hp = 745.7 W, 1 BTU/h = 0.293 W. The converter handles all standard power units.

    How to Use This Converter

    Using the Power Converter is simple: 1. Enter the numeric value you want to convert in the input field 2. Select the unit you are converting from using the first dropdown (available units: Watt (W), Kilowatt (kW), Megawatt (MW), Horsepower (hp), BTU per Hour (BTU/h), and 3 more) 3. Select the unit you are converting to using the second dropdown 4. Click "Convert" to see the result instantly 5. Use the "Swap" button to quickly reverse the conversion direction 6. View the "All Conversions" table to see the value in every available unit

    Example Conversions

    Here are some common conversions you can perform with this tool: 1 kW → ? hp, 1 hp → ? kW, 1 W → ? BTU/h Try clicking any of the "Popular Conversions" buttons above to instantly set up these conversions. For example, you can quickly convert between metric and imperial units, which is especially useful when working with international measurements or specifications.

    Benefits and Use Cases

    Important for automotive, industrial equipment, HVAC, and comparing engine or motor specifications across different unit systems.

    Common Mistakes to Avoid

    Avoid these common pitfalls when using the Power Converter: - Confusing mechanical horsepower with metric horsepower (they differ slightly) - Assuming watts and BTU/h are directly comparable (1 W ≈ 3.412 BTU/h) - Using the wrong conversion factor for older horsepower definitions - Confusing power (watts) with energy (watt-hours) Being aware of these issues will help you get accurate conversions every time.

    Frequently Asked Questions

    How many watts are in a horsepower?

    1 horsepower equals approximately 745.7 watts or 0.7457 kilowatts.

    What is the difference between energy and power?

    Power is the rate of energy transfer. Energy is measured in joules or kWh, while power is measured in watts (joules per second).

    How do I convert kilowatts to megawatts?

    Divide kilowatts by 1000 to get megawatts. For example, 1000 kW = 1 MW.

    What is the typical power consumption of household appliances?

    A refrigerator uses 100-400 W, a microwave 800-1500 W, and an air conditioner 2000-5000 W. LED bulbs use only 5-20 W.

    How do I convert BTU/h to watts?

    Multiply BTU/h by 0.293071 to get watts. For example, 10,000 BTU/h ≈ 2930 W.

    What is the difference between mechanical and metric horsepower?

    Mechanical horsepower (745.7 W) is used in the US, while metric horsepower (735.5 W) is used in Europe. Metric hp is about 1.4% smaller.

    How many horsepower does a typical car have?

    Most passenger cars have between 100 and 300 horsepower. Compact cars average 100-150 hp, while sports cars can exceed 500 hp.
