Walking 20,000 steps generally burns between 700 and 1,000 calories, depending on factors such as body weight, walking speed, and intensity.

• For example, a person weighing about 125 pounds burns roughly 675 calories walking 20,000 steps at 4 mph, while someone weighing 155 pounds burns around 835 calories, and a 185-pound person burns approximately 1,000 calories under the same conditions

• Since 2,000 steps roughly equal 1 mile, 20,000 steps correspond to about 10 miles of walking. The calories burned increase with weight and pace, so heavier individuals and faster walking speeds result in more calories burned

• On average, it takes about 2,000 to 3,000 steps to burn 100 calories, meaning 20,000 steps would burn about 700 to 1,000 calories for most people

In summary, walking 20,000 steps can burn approximately 700 to 1,000 calories, with exact values depending on individual characteristics and walking conditions.
