Answer 1

Try the following code that will change the displayed dimensions unit in front end:

add_filter( 'woocommerce_format_dimensions', 'custom_dimention_unit', 20, 2 );
function custom_dimention_unit( $dimension_string, $dimensions ){
    $dimension_string = implode( ' x ', array_filter( array_map( 'wc_format_localized_decimal', $dimensions ) ) );

    if ( ! empty( $dimension_string ) ) {
        $dimension_string .= ' ' . __('ft');
    } else {
        $dimension_string = __( 'N/A', 'woocommerce' );
    }

    return $dimension_string;
}

Code goes in function.php file of your active child theme (or active theme).

Update: Make dimension unit "ft" (feet) globally (everywhere)

Woocommerce dimension available units are "m", "cm", "mm", "in" and "yd".

But "ft" is not available in the Woocommerce > Settings > Products > Mesurements section.

What you can do is the following:

1. Paste the following line in your function.php file and save:

    update_option( 'woocommerce_dimension_unit', 'ft' );
   

2. Browse any page of your web site.

3. Remove or comment the line of code from your function.php file and save.

4. You can also remove the first code snippet as it's not needed anymore.

5. You are done.

You will get something like:

And in backend:
