3 hours to seconds

How to multiply and divide time in excel What format does the source data contain? hh:mm:ss or column for each part? I would convert everything into seconds, multiply, and then convert back to hh:mm:ss If you have minutes in one column (a) and seconds in another column (b), I would put in C1 =TRUNC((A1*60+B1)*F1), where F1 is the multiplier factor. ................
