Google MAP API v3: computeDistanceBetween method and distance in metric form
提问by Hellnar
I want to calculate the direct distance between to positions in metric form. (ie: from A to B in kilometers).
我想以公制形式计算位置之间的直接距离。（即：从 A 到 B，以公里为单位）。
I didn't understand what computeDistanceBetweenmethod returns in units.
我不明白computeDistanceBetween方法以单位返回什么。
Thanks
谢谢

It's in meters. To convert to kilometers divide by 10241000, obviously.
它以米为单位。转换为公里除以10241000，显然.
google.maps.geometry.spherical.computeDistanceBetween(
Moscow, Leningrad
); // 679601 m
By the way, the underlying code of this library method is based on the Haversine formula.
顺便说一下，这个库方法的底层代码是基于Haversine公式的。
