How to begin converting Time String to Number or D...

[Cody_Winchester]

I've been scouring this forum for an answer to a variant of "Convert String to Duration" but alas, no simple answers uncovered!

• In my case, I have a text field that contains duration as as string such as, "1:30:00."
• I need this to now be a field that is either a number (1.5), or an actual Duration type field.
• DATEADD(), DATETIME_PARSE(), DATETIME_FORMAT(), etc. formulas return errors and cannot format this particular representation of time as a string.

What incantation of formula language is required for Airtable to do this so I can use this data? Thanks!

I managed to decipher a solution within this post. It came down to using the VALUE() function and dividing by desired unit of time (/3600 to yield hours).
