短释义：
If you state your exact longitude, you are describing how far east or west you are of the Prime Meridian, the imaginary line of longitude which runs through Greenwich, England. When you add your latitude, anyone with a map can pinpoint exactly where you are in the world. If you’re standing at a latitude of 40°41.3’N and a longitude of 74°02.7’W, for example, you are at the Statue of Liberty.
在地理学中，经度是指通过南北两极平分地球的假想线（垂直延伸的线，而不是水平延伸的纬线，与赤道平行）。
长释义：
If you state your exact longitude, you are describing how far east or west you are of the Prime Meridian, the imaginary line of longitude which runs through Greenwich, England. When you add your latitude, anyone with a map can pinpoint exactly where you are in the world. If you’re standing at a latitude of 40°41.3’N and a longitude of 74°02.7’W, for example, you are at the Statue of Liberty.
如果您说出确切的经度，您就是在描述您距离本初子午线（穿过英国格林威治的假想经线）的东边或西边有多远。添加纬度后，任何拥有地图的人都可以准确定位您在世界上的位置。例如，如果您站在北纬 40°41.3’、西经 74°02.7′ 处，那么您就位于自由女神像处。
文学例句：
As we crossed the 180th degree of longitude, just half the 422 way around the world from the Royal Observatory at Greenwich, we “gained a day,” or rather, recovered one that we had lost.
当我们跨越经度 180 度时，距离格林威治皇家天文台仅绕地球 422 圈的一半，我们“赢得了一天”，或者更确切地说，恢复了我们失去的一天。

For explanation of the geographical sense, see latitude.also from late 14c.
下面是词源的翻译（机器翻译比较难翻，参考着看）
longitude(n.)late 14c.,“长度；高度”，也称为“天文或地理经度”，天空或地球表面东西向距离的度量，源自拉丁语 longitudo “长度，持续时间长”，源自 longus “长”（参见 long (adj.)）。有关地理意义的解释，请参阅纬度。也是从 14 世纪末开始。
