What is the conversion between horsepower and kilowatts for diesel engines?
2 Answers
Kilowatts and horsepower are converted at a ratio of 1 kilowatt (kW) = 1.36 horsepower (ps). The relevant explanations are as follows: Introduction: Power is not a unit of power, so it cannot be converted. The power unit of diesel engines is kilowatt, and 1 kilowatt (kW) = 1.36 horsepower (ps). Additional Notes: Horsepower is a commonly used unit for measuring power in engineering. It generally refers to metric horsepower rather than imperial horsepower. By convention, 1 metric horsepower is defined as the work required to lift a 75-kilogram object 1 meter in 1 second. Metric horsepower specifies that 1 metric horsepower is the work done in 1 second to complete 75 kilogram-force·meters of work.
The conversion between horsepower and kilowatts is quite common for diesel engines. There's a simple formula I always remember: 1 kilowatt ≈ 1.36 horsepower. For example, my tractor is labeled 90 kW, and a quick mental calculation by multiplying by 1.36 tells me it's about 122 horsepower. When repairing vehicles and encountering imported equipment labeled in horsepower, I just divide by 1.36 to convert to kilowatts. Remember that German engineer who helped us fix the harvester last year? He saw the dashboard displaying kilowatts and actually counted on his fingers to convert to horsepower - it was hilarious. These dual-unit standards are so common in construction machinery, veteran farm equipment mechanics with 20 years' experience can convert them instantly.
