What is the horsepower equivalent of an engine's maximum net power of 110kw?

110kw equals 147.5099hp (imperial horsepower) = 149.6ps (metric horsepower). Below is additional information: Detailed explanation of horsepower: The concept of horsepower as a unit was coined by James Watt, the improver of the steam engine, to represent the power of his steam engine relative to the pulling force of horses. It is defined as "the power of a horse capable of pulling 33,000 pounds at a speed of one foot per minute," with the standard units being watts (W) or kilowatts (kW). The metric horsepower is set very close to the imperial horsepower, defined as the work done to lift 75 kilogram-force·meters in one second. That is: 1 metric horsepower = 75 kilogram-force·meters/second = 735 watts. Imperial horsepower: Countries like the UK and the US use the imperial horsepower. 1 imperial horsepower equals 550 foot-pounds/second, equivalent to 745.7 watts. In the late 18th century, British physicist Watt (1736-1819) defined horsepower to measure the power of newly manufactured steam engines, setting it as the work required to lift a 1000-pound weight by 33 feet in one minute. This is the imperial horsepower, denoted by the letter HP. More vividly, if a person carries a 10kg load and runs 100 meters in 13.3 seconds, their power output is 1 horsepower. Instantaneous bursts (like dunking a basketball) can reach up to 2 horsepower. In daily life, the unit "P" used for air conditioners also refers to horsepower; a 1P air conditioner is sufficient for a bedroom, while microwaves and electric kettles can reach up to 2P.
As someone who frequently shares automotive knowledge, I deeply understand the importance of power unit conversion. When converting 110 kilowatts of maximum net power to horsepower, the standard conversion factor for metric horsepower (PS) is approximately 1 kW ≈ 1.36 PS. Therefore, 110 multiplied by 1.36 equals roughly 149.6, which rounds up to about 150 horsepower. In the automotive field, 150 horsepower is considered a mid-range level, suitable for many family cars, such as the base engine versions of the Volkswagen Golf or Toyota Corolla. In actual driving, this power provides smooth acceleration, effortless highway overtaking, and relatively low fuel consumption, typically around 7-8 liters per 100 kilometers. Horsepower also affects engine lifespan and maintenance frequency—a 150-horsepower car can reliably operate for many years with proper upkeep. From a broader automotive market perspective, such engines strike a good balance between performance and economy, making them ideal for daily commuters.
