Walking is the easiest cardio there is — no equipment, every day. This tool converts the step count from your phone or pedometer into calories burned and distance walked, so you can see in numbers what today’s 10,000 steps achieved and feed it straight into a weight-loss plan.
How to use this tool
Enter your steps and weight, and pick a walking speed. Adding your height improves the distance estimate via stride length (≈ height × 0.45). Results show both gross calories (including resting metabolism) and the net extra burned by walking.
How many steps per day?
Japan’s Health 21 program targets about 8,000 steps a day for adults, and meta-analyses suggest mortality-risk reduction starts to plateau around 7,000–8,000 steps. Starting with +1,000–2,000 steps over your current level is realistic. A 60 kg person walking 10,000 steps (~7 km) burns roughly 300 kcal gross.
Tips
Walking calories help a cut, but walking alone loses weight slowly. Track your daily total with the TDEE Calculator and plan the balance with the Weight Change Simulator.
How far is 10,000 steps?+
A common stride estimate is height × 0.45: about 74 cm at 165 cm tall (10,000 steps ≈ 7.4 km) or 79 cm at 175 cm (≈ 7.9 km). Enter your height and this tool applies that formula.
How many calories do 10,000 steps burn?+
Heavier bodies and faster walking burn more. That is about 1–1.5 rice balls (180 kcal each).
What is the difference between gross and net calories?+
Net is more precise for diet math, but most apps display gross, so this tool shows both.
How many steps a day are healthy?+
Recent meta-analyses find risk reduction starts to plateau around 7,000–8,000 steps — you don’t need 20,000. Even +1,000 steps over your current level helps.
Are phone step counters accurate?+
They can miscount vehicle vibrations as steps, but for tracking trends (more than last week?) the accuracy is plenty.
・Calories (kcal) = MET × weight (kg) × time (h). Walking METs: 4.0 km/h = 3.0 / 4.8 km/h = 3.5 / 5.6 km/h = 4.3 (Ainsworth BE, et al. (2011). 2011 Compendium of Physical Activities.)
・Distance (km) = steps × stride (m) ÷ 1000, stride ≈ height × 0.45

Calories and distance are estimates from general coefficients; actual values vary with gait, terrain and body composition. For medically supervised exercise, follow your doctor’s guidance.
