如何将 Power BI 中的小时、分钟、秒转换为分钟？答案

【问题标题】：How to convert hours, minutes, second in PowerBI to minutes?如何将 Power BI 中的小时、分钟、秒转换为分钟？

【问题描述】：

大家好，

我有一个名为 Table1 的表格，其中有一列显示学生完成考试所用的时间（如上面的屏幕截图所示）。我可以知道如何将列转换为分钟吗？基本上需要将hrs（如果存在）转换为分钟并将sec转换为分钟。

为了简化输出，如果sec大于等于30sec，则算作1分钟，否则忽略sec。我还是 PowerBI 的新手，任何帮助将不胜感激！

感谢您的解决方案！它适用于大多数数据，但是当涉及到 1hrs 47sec 、 25min 或 1hrs 时，输出是错误的。我应该如何更改它以使其适合所有条件？
@weizer，检查更新的代码。如果有帮助，请接受答案并投赞成票。
我尝试了最新的代码，但似乎还是一样，我在我的问题中附上了输出的屏幕截图。 25min 和 1hrs 47sec 仍然会出错
哦，知道了。你有时间在一些其他的模式。我会检查的。你也只有像“25 sec”这样的秒吗？
