好英语网1海里等于多少米
一海里是一个用于测量距离的单位，尤其在海洋和航海领域得到广泛使用。在国际标准中，1海里被定义为1852米，或者约合1.15英里。海里源自古代的航海测量方法，它最初是通过观测海上的纵横交错的石头或其他物体来估算船只所行进的距离。
One nautical mile equals how many meters
A nautical mile is a unit of measurement used primarily in the fields of maritime and navigation. In the international standard, 1 nautical mile is defined as 1852 meters, or approximately 1.15 miles. The nautical mile originated from ancient methods of maritime measurements, where it was initially estimated by observing the intersecting stones or other objects on the sea to measure the distance travelled by ships.
海里作为距离单位在海洋和航海领域发挥着重要的作用。由于船只在海上航行时往往会受到风浪、海流等自然因素的影响，普通的长度单位如千米或英里并不能准确地描述船只实际行进的距离。相比之下，海里则更适合用于海洋导航和航海测量。
The nautical mile plays a significant role as a unit of measurement in the fields of maritime and navigation. As ships are often affected by natural factors such as winds, waves, and currents while sailing on the sea, conventional length units like kilometers or miles cannot accurately describe the actual distance covered by a ship. In comparison, the nautical mile is more suitable for marine navigation and maritime measurements.
在现代航海中，1海里被定义为地球子午线上1分角度所对应的弧长。这种定义方法使得每个经度圈的纬线弧长都是相等的，这样方便了航海者在不同纬度之间进行距离测量和导航。此外，海军、海岸警卫队和渔业部门也广泛使用海里作为重要的度量单位。
In modern navigation, 1 nautical mile is defined as the arc length corresponding to 1 minute of angle along a meridian of the Earth. This method of definition ensures that the arc lengths of the parallel circles of latitude are equal, facilitating distance measurement and navigation between different latitudes. Additionally, the nautical mile is widely used as a crucial measurement unit in naval, coast guard, and fisheries sectors.
值得一提的是，尽管国际上已经有了统一的海里定义，但在不同国家或地区，仍然存在着一些不同的海里定义。例如，美国海军将1海里定义为1853.18米，稍微超过国际标准。因此，在具体使用时，需要注意所使用的海里定义是否与国际标准一致。
It is worth mentioning that although there is a unified definition of the nautical mile internationally, there are still some regional variations in nautical mile definitions in different countries or regions. For example, the U.S. Navy defines 1 nautical mile as 1853.18 meters, slightly exceeding the international standard. Therefore, when using nautical miles, it is essential to pay attention to whether the definition used aligns with the international standard.
总之，1海里等于1852米，或者约合1.15英里。作为海洋和航海领域的主要度量单位，海里在海上导航、船舶测量和海洋研究中发挥着重要的作用。它的定义使得航海者能够更准确地测量和描述海上距离，保证船只安全航行。
In conclusion, 1 nautical mile equals 1852 meters or approximately 1.15 miles. As a primary unit of measurement in the maritime and navigation fields, the nautical mile plays a vital role in marine navigation, ship measurements, and oceanographic research. Its definition enables navigators to measure and describe distances at sea more accurately, ensuring the safe passage of ships.
