Power Converter

What is the Power Converter?

Convert any power unit to all others at once — W, kW, hp, BTU/h. Power units such as watts, kilowatts, horsepower and BTU per hour describe how quickly energy is used or produced.

How to use the Power Converter

1. Enter your value, your from unit.
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: watt (w), kilowatt (kw), horsepower (hp), btu per hour (btu/h).
4. Check the chart to see how the conversion scales.

Formula and method

Worked example

With value = 1, from unit = Watt (W), the Power Converter returns watt (w): 1 W; kilowatt (kw): 0.001 kW; horsepower (hp): 0.0013410220896 hp.

When an all-in-one power converter helps

You are comparing a car engine rated in kilowatts with one rated in horsepower. Converting shows which is more powerful.

A homeowner compares an air conditioner rated in BTU per hour with electric heaters rated in watts.

Watch out for these mix-ups

• Confusing power with energy.
• Mixing metric and mechanical horsepower.
• Comparing BTU with BTU per hour.
• Rounding ratings too much.

Tips for better results

• Remember 1 hp ≈ 746 W.
• Use kW for electrical comparisons.
• Check whether ratings are input or output.

💡 Practical tip: One mechanical horsepower is about 746 watts, so a 100 kW electric motor is roughly 134 hp.
