Converting between centimeters and inches in Airtable

Hey everyone, I’m working on a project in Airtable and I’m stumped. I want to set up two cells that can convert between centimeters and inches automatically. Right now, I’ve got a workaround using a third cell with an ‘if’ function to show both units when I fill in either of the other cells. But it feels clunky. Is there a smoother way to do this without needing that extra cell? I’d love to just type in one measurement and have the other update on its own. Any tips or tricks would be super helpful! Thanks in advance for your ideas.

hey tom, have u tried using airtable’s formula field? u could set up 2 formula fields, one for cm and one for inches. each field can check if the other has a value and convert it. that way u dont need an extra cell. just input in either field and the other updates automatically. hope this helps!

I’ve encountered a similar challenge in my Airtable projects. One efficient solution is to utilize Airtable’s scripting capabilities. You can create a simple script that automatically performs the conversion when a value is entered in either the centimeter or inch field. This approach eliminates the need for additional cells or complex formulas. The script can be triggered on field changes, ensuring real-time updates. While it requires a bit more setup initially, it provides a cleaner, more streamlined solution in the long run. If you’re not familiar with scripting, Airtable’s documentation offers helpful guides to get you started.

As someone who’s been using Airtable for years, I’ve found a neat trick for this exact situation. Instead of using formula fields or scripts, I leverage Airtable’s automation feature. Here’s what I do:

I set up two number fields - one for cm and one for inches. Then, I create two automations. The first triggers when the cm field is updated, calculating and filling the inch field. The second does the reverse when the inch field is updated.

This method is straightforward, doesn’t require coding, and works seamlessly in the background. It’s especially useful if you’re dealing with large datasets or frequent updates. The conversions happen instantly, and you can input values in either field without thinking about it.

One caveat: make sure you don’t create an infinite loop by having both automations trigger each other endlessly. Set conditions carefully to avoid this. It’s a powerful solution that’s served me well in various projects.
