About KW in PS
Fast, transparent, and accurate automotive power calculation tools designed for vehicle owners, buyers, mechanics, and motoring enthusiasts.
Our Mission & Purpose
Motor vehicle power ratings can be confusing. Official European vehicle registration papers use the statutory International System of Units (SI) measure—Kilowatts (kW)—while vehicle brochures, classified ads, and car enthusiasts frequently discuss engine output in Pferdestärke (PS) or brake horsepower (bhp).
We created KW in PS to provide an instant, reliable, and accessible conversion platform. Whether you are verifying power in a vehicle registration document (*Fahrzeugschein*), checking learner license power caps, or comparing EV specifications, our tools deliver instant clarity without complexity.
