Steps to Calories Calculator

In four steps: it estimates your stride length from your height (height in cm x 0.413), multiplies that by your step count to get distance, divides distance by an assumed speed for your selected pace to get time, then applies the standard MET formula -- MET x weight in kg x time in hours -- to get calories. For 10,000 steps at 170 cm height, 70 kg, moderate pace, that works out to roughly 374 kcal.

Because two effects work against each other. A faster pace has a higher MET (intensity), but it also covers your fixed step count in less time. For 10,000 steps, slow, moderate and brisk pace all land in a fairly similar calorie range because the extra intensity of a faster pace is partly offset by spending less time walking -- it's total time-under-activity that matters, not the MET number alone.

The 0.413 x height formula is a widely used pedometer-industry approximation, not a measurement of your actual stride. It's a reasonable population average, but it tends to overstate stride -- and therefore distance and calories -- for anyone who takes shorter steps than their height would predict, which is common in older adults or after certain orthopedic conditions.

No -- the calculation assumes flat, level ground. Stair climbing, incline walking and uneven terrain all burn meaningfully more energy per step than this model accounts for, so treat this calculator as a flat-ground walking or running estimate, not a general activity tracker.

Treat it as a rough activity gauge, not a precise figure to bank against food intake. Consumer step counters themselves carry meaningful error (commonly cited in the 15-25% range) before this calculator's own stride and MET approximations are layered on top, so the combined number is best used to compare your own days and paces against each other, not as an exact calories-in-calories-out input.
