Excel will interpret a pace as a time by default, so entering 7:40 00 will become 7:4000:00 AM, which will mess things up. Enter any paces with a preceding quotation mark such as ‘7:40 00 to make it textual.  [[File:783147754 WpFmi-O.jpg]]  To convert a pace to the number of seconds use =HMS2S(cell), such as =HMS2S(B1B2). To convert seconds to a pace use S2MS for minutes:seconds, or S2HMS for hours:minutes:seconds.  If you wanted to add five seconds per mile, use =S2MS(HMS2S(b1B2)+5) [[File:783147770 SoM3Q-O.jpg]] ==Saving a file with Macros==To save an excel file that contains macros, you have to save it as a '.xslm' file.  [[File:786106685 MJMUP-O.jpg]] ==Loading a file containing macros==By default, macros are disabled when you load an excel file. You will see a security warning with an options box. To enable the macros, click on 'options' and select 'enable this content'. If you do not enable the content, the macros will result in an Excel error '#NAME?' [[File:786107613 kSYvf-O.jpg]] ==Troubleshooting== If you get an error saying #VALUE? like this [[File:786110756 4dKCW-O.jpg]] The problem is probably that you have the wrong data type. In the case above, the macro S2MS (seconds to Minutes:Seconds) requires an integer number of seconds, not a 'minutes:seconds' value. Equally MS2S requires Minutes:Seconds to work correctly.  ==Brief Documentation=={| {{table}}|- | Macro || Usage|- |S2HMS ||Convert number of seconds to hours:minutes:seconds|- |S2MS ||Convert number of seconds to minutes:seconds|- |HMS2S||Convert hours:minutes:seconds or minutes:seconds to number of seconds|- |PaceToMPH||Convert minutes:seconds as minutes/mile to miles per hour|}
