If someone asks you your WEIGHT what would you answer in SI Units.

  1. My weight is x 'kilogram'
  2. My weight is x 'Newton'.

As we know that weight is a force due to local acceleration and still most people say it in kilogram will you correct them or you prefer to stick to the wrong way of saying even after knowing.
