Estimate calories burned from your daily step count, weight, and stride length.
This tool estimates calories burned from a step count, using your weight and stride length to first estimate distance and time, then applying the standard MET-based walking energy-expenditure formula.
Enter your steps, weight in kilograms, and stride length in meters (an average adult stride is roughly 0.7-0.8m). Estimated distance and calories burned appear instantly.
Distance = Steps × Stride Length
Calories/min = (MET × 3.5 × Weight(kg)) / 200, MET = 3.5 for brisk walking
Track how your daily step count translates to calorie burn as part of a broader activity/calorie plan. For a direct distance conversion without the calorie estimate, see the Steps to Miles Calculator.
Take the default inputs as a hypothetical case: 10,000 steps, a body weight of 70 kg, and a stride of 0.75 m. First the tool converts steps to distance: 10,000 x 0.75 = 7,500 m, or 7.5 km. It then assumes an average walking speed of 5 km/h, so 7.5 km takes 90 minutes. Energy use per minute is (3.5 x 3.5 x 70) / 200 = 4.2875 kcal, and 4.2875 x 90 gives roughly 386 kcal. The kilometer figure and the calorie figure are the two tiles you see.
Minutes = (Distance in km / 5) x 60. Calories = (3.5 x 3.5 x Weight / 200) x Minutes
Now change one input at a time. A 90 kg walker taking the same steps at the same stride gets about 496 kcal, because the energy figure scales in direct proportion to weight. A 70 kg walker with a shorter 0.65 m stride covers 6.5 km and burns about 334 kcal, since fewer meters mean fewer estimated minutes. Because both distance and time follow from stride length, stride is an influential input here.
Weight must be in kilograms; divide pounds by 2.2046 if needed. Stride length must be in meters, which is easy to get wrong if you know it in inches or feet (30 inches is about 0.76 m). To measure it, walk a marked distance such as 20 meters at your normal pace, count the steps, and divide the distance by the count. If your tracker also reports distance, you can compare it with the distance tile here to see whether the tracker is using a different stride than yours.
Treat the result as a ballpark, not something to eat back one for one. Many people overestimate exercise burn and underestimate food intake, so if you are managing weight, use the figure as one part of a larger plan and watch actual trends over several weeks. People with a medical condition, pregnancy, or a specific dietary goal should get calorie targets from a doctor or registered dietitian. This page is educational only.
The tool also helps set goals: if you want a walk that burns around a certain amount, you can adjust the step count until the calorie tile matches, then decide whether that is realistic for your day.
It's a reasonable estimate based on standard walking MET values, but actual calorie burn varies by individual fitness level, walking surface, incline, and pace -- treat it as a useful approximation, not a precise measurement.
Roughly 0.7-0.8 meters for an average adult, though it scales with height and leg length -- taller people generally have a longer natural stride.
This tool assumes a typical average walking speed; walking faster or slower than that pace would change actual calorie burn somewhat from the estimate shown.
Weight and stride both enter the formula. Heavier people use more energy per minute, and a longer stride means more distance and therefore more estimated walking time for the same number of steps.
It is built around brisk walking at 5 km/h. Running steps cover more ground per minute and use more energy, so for a run use the Calories Burned Running Calculator, which takes weight and duration.
Each tool uses the unit that fits its output: this one works in kilometers and kilograms, while the miles tool works in inches. Convert your stride before entering it; 1 inch equals 0.0254 m.
Neither is exact. A watch may account for heart rate or pace, while this tool uses a fixed pace and intensity. If they differ, that is normal; consistency of method matters more than either absolute number.
