Power Converter
Convert power between watts, kilowatts, horsepower, and metric PS with exact scientific constants.
Power Converter
Bidirectional browser-based conversion with verified scientific standards.
About this tool
The Power Converter translates energy transfer rates between Watts (W), Kilowatts (kW), Megawatts (MW), Mechanical Horsepower (hp), Metric Horsepower (PS), and BTUs per hour (BTU/h).
Engineers, automotive enthusiasts, and facility managers regularly convert between mechanical horsepower and electrical kilowatts (1 hp ≈ 745.69987 Watts) when sizing motors, engines, and electrical generators.
Enjoy instantaneous client-side calculation with no network delay. High-contrast displays and quick-copy buttons ensure fast, error-free documentation.
概要
Our suite of unit converters provides instant, bidirectional measurement calculations across engineering, scientific, computing, automotive, and culinary domains.

よくある質問
How accurate are the unit conversions?
All unit conversions use exact international scientific constants defined by the International System of Units (SI), NIST, and ISO standards (e.g., 1 acre = 4046.8564224 m², 1 bar = 100,000 Pa, and 1 hp = 745.69987 Watts). Computations are performed in 64-bit IEEE 754 floating-point precision.
How does the Cooking Converter handle ingredient densities?
Because kitchen ingredients vary in density, a volumetric cup of flour weighs approximately 120 grams while a cup of granulated sugar weighs approximately 200 grams. Our cooking converter incorporates ingredient-specific density factors so you can accurately convert between weight (grams/ounces) and volume (cups/tablespoons).
Why do decimal gigabytes (GB) differ from binary gibibytes (GiB)?
Storage drive manufacturers use the decimal system where 1 GB = 1,000,000,000 bytes (10^9). Operating systems such as Windows calculate storage using the binary IEC system where 1 GiB = 1,073,741,824 bytes (2^30). Our data storage converter bridges this gap, showing exact equivalents across decimal and binary standards.
How does the fuel economy conversion work between MPG and L/100km?
Miles per Gallon (MPG) measures distance per unit volume, whereas Liters per 100 Kilometers (L/100km) measures volume consumed per fixed distance. Because these metrics are inversely related, the formula uses reciprocal division: L/100km = 235.214583 / US_MPG. Lower L/100km indicates better efficiency.
Can I adjust decimal precision or copy conversion results?
Yes. You can select between 2, 4, or 6 decimal places of precision. A dedicated Copy button lets you transfer the converted value directly to your clipboard with one click.
