It is possible to append a calculation field with text so it displays the values.
Ex: Field A x Field B = Field C and field C is a number field showing the result of the calculation. We want to add “Sq. Ft” after the calculation so the answer looks like “1,000 Sq. Ft” and not just “1,000”
I used the pseudo element :after to put the “Sq. Ft” after the input. The form ID and field ID are specific to my form (form 118 and field 4) so you will need to adjust for your form. Also, you may need to adjust the appearance of the field under the Appearance tab in the form editor, to make it small, medium or large. Or, you could add additional CSS to give it a fixed width when it is rendered.
