Woocommerce add labels to custom dimension unit on front end

Question

Need to implement custom dimension labels for custom dimensions output on front end.

I have found codes below which work well on their own but not together, so trying to implement the two into 1 compatible code.

• code 1. Outputs woocommerce product dimensions on frontend in both units "CM" & "IN" x2 custom dimension units without custom labels

Code 1.

add_filter( 'woocommerce_format_dimensions', 'custom_format_dimensions', 10, 2 );
function custom_format_dimensions( $dimension_string, $dimensions ){
    // Initializing variable
    $dimentions2 = array();

    // Loop though dimensions array (and set custom converted formatted decimals values in a new array)
    foreach( $dimensions as $key => $value ){
        if( ! empty($value) && $value != 0 )
            $dimentions2[$key] = wc_format_localized_decimal( round($value * 2.54, 2) );
    }

    // Format default dimentions in a string
    $dimension_string  = implode( ' x ', array_filter( array_map( 'wc_format_localized_decimal', $dimensions ) ) );

    if ( ! empty( $dimension_string ) ) {
        // Format custom converted array in a string and append it to default formatted dimensions string
        $dimension_string2 = ' ( ' . implode( ' x ', $dimentions2 ) . ' ' . __( 'in', 'woocommerce' ) . ' )';
        $dimension_string .= ' ' . get_option( 'woocommerce_dimension_unit' ) . $dimension_string2;
    } else {
        $dimension_string = __( 'N/A', 'woocommerce' );
    }

    return $dimension_string;
}

• Code 2. Add custom labels to output dimensions. For example "D X W X H (cm)" & "D X W X H (in)" Woocommerce dimension units with custom labels

add_filter( 'woocommerce_format_dimensions', 'custom_formated_product_dimensions', 10, 2 );
function custom_formated_product_dimensions( $dimension_string, $dimensions ){
    if ( empty( $dimension_string ) )
        return __( 'N/A', 'woocommerce' );

    $dimensions = array_filter( array_map( 'wc_format_localized_decimal', $dimensions ) );

    return 'D'.$dimensions['length'].' x W'.$dimensions['width'].' x H'.$dimensions['height'].' (cm)';
}

How to make code 1 output with code 2 labels? I have tried for many hours replacing dimensions array etc from one snippet to the other but no luck. Any help would be very much appreciated.
