Building a formula from a formula (square footage calcs

[Zach_Ware]

I have a weird one. I’m building a table of square footage calculations from a census of product types.

I have a single select field for unit dimensions, like 10x20. And another field of the quantity of those units.

So in an example of a 10x20 with 10 in the qty field, the proper formula construction would be =102010 for an output of 2000.

I built a formula as a test to see if I could replace the x with a * to get closer to automating the math, but I can’t find a way to get that into a formula that then parses the * as a multiplier and does the full calculation.

I’m missing some kind of step to get there. Any advice?

I like your thinking. It’s a way of getting to the answer that I wouldn’t have thought of. You need an Airtable function like EVALUATE() that would take a string and evaluate as a formula. Would be cool.

Here’s another way to get what you want, though decidedly less elegant.
