Power Converter - Convert kW, hp, and Watts Accurately
Convert between different power units including watts, horsepower, BTU, and other power measurements
Power is a fundamental concept in science, engineering, and daily life. It measures the rate at which work is done or energy is transferred. Across the world, different units are used for power, including watts (W), kilowatts (kW), and horsepower (hp).
A power converter allows you to easily switch between these units. Whether you want to convert kW to hp, watts to kilowatts, or hp to kW, having an accurate tool ensures precision in engineering, automotive, and electrical applications.
Why Use a Power Converter?
- Accurate formulas: Based on SI and imperial system definitions.
- Multiple conversions: Covers watts, kilowatts, horsepower, and more.
- Instant results: Save time by avoiding manual calculations.
- User-friendly: Simple steps, clear results.
- Wide applications: Useful in electrical engineering, automotive industry, and physics.
How to Use the Power Converter
- Enter the value in your known unit (W, kW, hp).
- Select the unit you want to convert to.
- Get the result instantly.
- Apply it in calculations for motors, engines, or electrical systems.
Common Units of Power
Watt (W)
- SI base unit of power.
- 1 W = 1 joule per second.
- Used in small appliances, electronics, and physics.
Kilowatt (kW)
- 1 kW = 1000 W.
- Common for household appliances, motors, and generators.
- Often used to measure electric consumption.
Horsepower (hp)
- An imperial unit of power.
- 1 hp = 745.7 W (mechanical).
- Used in automobiles, engines, and heavy machinery.
Power Conversion Formulas
kW to hp
hp = kW × 1.341
Power Conversion Example:
10 kW to hp
hp = 10 × 1.341 = 13.41 hp
hp to kW
kW = hp × 0.7457
Example:
20 hp to kW
kW = 20 × 0.7457 = 14.91 kW
W to kW
kW = W ÷ 1000
Example:
5000 W to kW
kW = 5000 ÷ 1000 = 5 kW
kW to W
W = kW × 1000
Example:
2 kW to W
W = 2 × 1000 = 2000 W
Applications of Power Conversion
- Automotive Industry: Car engines are rated in hp in the US and kW in Europe. Converting values ensures comparisons.
- Electrical Systems: Motors and generators list ratings in kW or W, but engineers sometimes need hp values.
- Construction & Industry: Heavy machines and pumps use both SI and imperial units.
- Household Appliances: Devices like heaters, ACs, and microwaves are rated in W or kW.
- Education & Research: Students and researchers use converters in energy and mechanics problems.
Quick Reference Table for Power Conversion
Kilowatts (kW) | Horsepower (hp) | Watts (W) | Kilowatts (kW) |
1 kW | 1.341 hp | 1000 W | 1 kW |
5 kW | 6.71 hp | 5000 W | 5 kW |
10 kW | 13.41 hp | 10,000 W | 10 kW |
20 kW | 26.82 hp | 20,000 W | 20 kW |
