[Plugin: Calculated Field Form] add unit behind value

Dear all,

I am new with WordPress and I am trying to make a small converter tool on my website, for which I am using the Calculated Field From plugin.

At the calculation field you can set something behind the calculated value, this is called “Symbol to display at the end of calculated field”. But this is a static value. I want to be able to change this value according a different field, which is a dropdown menu. Is this possible?

I want this because if you for instance convert a number to mm or meters or inch I want to put the correct unit behind the value.

What can I do to make this possible?

Best regards,

Sil
