The short answer: Hungry Jack's publishes kilojoules (kJ), not calories. In its official guide, a Whopper is 2,437 kJ (280 g serving) and a Hamburger is 1,192 kJ. To give calories we divide kJ by 4.184, so the Whopper is about 582 Cal. Those Cal figures are our conversion, not Hungry Jack's numbers. Figures below come from Hungry Jack's Nutritional Guide PDFs and can change when recipes or serve sizes change.
