程序将以公里/小时为单位的速度转换为米/秒，反之亦然-yiteyi-C++库

将以公里/小时为单位的速度转换为米/秒，反之亦然。例如：

null

Input : kmph = 72, mps = 10Output : speed_in_mps = 20         speed_in_kmph = 36 Input : kmph = 54, mps = 15Output : speed_in_mps = 15         speed_in_kmph = 54

推荐：请尝试你的方法 {IDE} 首先，在进入解决方案之前。

方法： 1公里=1000米，1小时=3600秒（各60分钟×60秒）。从公里/小时到米/秒的转换- 将公里/小时转换为米/秒时，速度乘以1000，结果除以3600。

1 km/hr = 5/18 m/sec or 0.277778 m/sec

从米/秒到千米/小时的转换- 将米/秒转换为千米/小时时，速度除以1000，结果乘以3600。

1 m/sec = 18/5 km/hr or 3.6 km/hr
