我不知道如何合并这两个公式。我在短片中显示的问题的公式是：

公式1：
{=TRUNC(SUM(IFERROR(LEFT(C1:C577,FIND(" ",C1:C577)-1)*10^(MATCH(RIGHT(C1:C577,2),{"KB","MB","GB","TB"},0)*3),0))/(10^(INT((LEN(SUM(IFERROR(LEFT(C1:C577,FIND(" ",C1:C577)-1)*10^(MATCH(RIGHT(C1:C577,2),{"KB","MB","GB","TB"},0)*3),0)))-1)/3)*3)),2)&" "&INDEX({"KB","MB","GB","TB"},INT((LEN(SUM(IFERROR(LEFT(C1:C577,FIND(" ",C1:C577)-1)*10^(MATCH(RIGHT(C1:C577,2),{"KB","MB","GB","TB"},0)*3),0)))-1)/3))}
公式2：
{=TRUNC(SUM(IFERROR(LEFT(C1:C577,FIND(" ",C1:C577)-1)*10^(MATCH(RIGHT(C1:C577,2),{"KB","MB","GB","TB"},0)*3),0))/(10^(INT((LEN(SUM(IFERROR(LEFT(C1:C577,FIND(" ",C1:C577)-1)*10^(MATCH(RIGHT(C1:C577,2),{"KB","MB","GB","TB"},0)*3),0)))-1)/3)*3)*1.024),2)&" "&INDEX({"KB","MB","GB","TB"},INT((LEN(SUM(IFERROR(LEFT(C1:C577,FIND(" ",C1:C577)-1)*10^(MATCH(RIGHT(C1:C577,2),{"KB","MB","GB","TB"},0)*3),0)))-1)/3))}
我认为解决方案是在《 IF声明》中。
{=IF(WHAT_TYPE_HERE,Formula 1:,Formula 2:)}
