conversations.value: Can you explain how to solve this math problem: A store sells 20 packets of 100 grams of sugar every week. How many kilograms of sugar does it sell every week?
conversations.from: assistant
conversations.value: A total of 20 x 100 = 2000 grams are sold every week.
  Since 1 kilogram is equal to 1000 grams, then 2000/1000 = 2 kilograms of sugar are sold every week.
