Or, even better, just divide by the HMS form for 1 second (0@ 0' 1"): 

| - | - | - | 1@ 11' 37" | - | - | - | 4297 |
#+TBLFM: $8=$4 \ 0@ 0' 1"

Note that \ is integer division, so there is no need for a format conversion

P.S. I highly recommend reading the [[info:calc#Basic Arithmetic]] section of the calc manual

Hi Ryan

Convert to degrees, then multiply by 3600: 

| - | - | - | 1@ 11' 37" | - | - | - | 4297 |
#+TBLFM: $8=3600 deg($4); %d

Cheers

If an org table cell contains the HMS 1@ 11' 37"

is there an easy way to get the total (time)seconds?

(1*3600 + 11*60 + 37 = 4297)


if $4 =  1@ 11' 37"

how do I get $8 = 4297?

thanks
