14000 steps, about 7 km-9. 1 km. This problem involves step size. A stride is a distance of one step, calculated from the center of the foot. After one step, the distance between the centers of two feet is a person's stride. A person's stride is related to height and gender. Tall people take longer strides. Men stride longer than women.

The normal stride of an adult male is about 0.65 meters, and that of an adult female is about 0.50 meters. Therefore, 14000 step is approximately equal to: 14000 step x 0.50m/ step = 7000m, that is, 7km is approximately equal to: 14000 step x 0.65m/step = 91step.

How many calories does 10,000 steps consume? Ten thousand steps can consume about 240-300 kilocalories. The total calorie intake of human body every day is about 1, 800-2,000 calories, and the calories consumed by walking 10,000 steps are equal to 1/7 of the total calorie intake. For most people, except for the calories consumed in normal life (about 1.500- 1.700 kcal), walk 10000 steps every day.

Of course, how many calories are consumed by walking is also related to the speed of walking. Slow walking consumes less calories, while fast walking consumes more calories.
