In which folder of woocommerce 2.5.2 or of the plugin woocommerce-measurement-price-calculator I should insert the file wc-measurement-price-calculator-custom-unit.php ?

Im a bit confused, with Matteoraggi with this one. I've tried putting it in theme function.php and that didn't seem to work

So, I ran into the same problem mentioned above. I followed example listed on the woocommerce development site (, but to no avail. However, when I forced it into the array by calling the $key as well, that made all the difference.

foreach ( $settings as $key => $setting ) {
     if ( 'woocommerce_measurement_unit' == $setting['id'] ) {
         $settings[$key]['options']['league'] = __( 'league' );  // new unit

I'm a bit confused why this is the case because there are plenty of times that I can remember where I've looped through the array and set the new value using the 'current instance' of the loop, but I guess not this time. I'm not sure if it's a php version difference, but in any case, this worked for me. I hope this helps!
