Define a field type of measured value.

Code

function mvf_entityreference_field_instance_settings_validate($form, &$form_state) {

  // Entityreference module holds here instance array definition. Since in our
  // case it's just a sub field, we have to pass it through mocking up
  // sub field function.
  $field = $form['#mvf']['field'];
  $instance = $form_state['entityreference']['instance'];
  $form_state['entityreference']['instance'] = mvf_instance_mockup($field, $instance, 'unit');
