马力和千瓦之间的差异

马力与千瓦

马力和千瓦是用于测量系统功率的两个单元。这些单元被广泛用于发电，电动工程，机械工程甚至汽车技术等领域。为了充分理解这些领域，对这些概念有清晰的理解至关重要。在本文中，我们将讨论什么马力和千瓦，它们的定义，相似之处，马力和千瓦的应用以及马力和千瓦之间的差异。

千瓦

千瓦是单位用来测量能力。以下stand the concept of power, one must first understand the concept of energy. Energy is a non-intuitive concept. The term “energy” is derived from the Greek word “energeia” which means operation or activity. In this sense, energy is the mechanism behind an activity. Energy is not a directly observable quantity. However, it can be calculated by measuring external properties. Energy can be found in many forms. Kinetic energy, thermal energy and potential energy are to name a few. Power is the rate energy generation or conversion. The units of power are joules per second. This unit is also known as watt. A unit of thousand watts is known as a kilowatt. Watt is the SI unit for measuring power. The symbol used to identify watt is W while the symbol for the kilowatt is KW. The unit watt is named in honor of the physicist James Watt who was a great contributor to the field of energy. Since wattage is the rate of power, the wattage multiplied by the time gives the energy. The unit kilowatt-hour is used in electricity, to identify energy.

马力

马力是用于测量功率的单元。用来表示马力的术语是HP。最初创建了单元马力，以比较汽船和截骑兵的力量。即使SI系统是大多数国家 /地区的标准测量系统，马力仍然是汽车，电动机和许多其他机械设备中最常用的动力单元。马力的价值从735.5瓦到750瓦不等，具体取决于定义。汽车工程中马力最重要的定义之一是制动马力或必和必拓。制动马力是发动机的力量，没有变速箱和其他设备。其他形式的马力包括度量马力，PS，简历，锅炉HP，电气HP等。对于发动机，功率等于扭矩的乘积和发动机的频率乘以恒定的乘积，具体取决于所使用的单元。

马力和千瓦之间有什么区别？ •Kilowatt是SI（度量）系统中使用的单元，而马力不是标准单元。 •马力不是定义明确的单元，但千瓦是一个定义明确的单元。 •马力具有多种形式，例如断路马力，公制马力，锅炉马力等。千瓦仅采用一种形式。 •单位马力广泛用于汽车行业，而千瓦广泛用于电气系统。
