Steps to Distance and Calories

A pedometer or smartwatch gives you a step count, but what does that actually mean in distance and energy? This calculator converts raw step data into kilometres, miles, and an estimated calorie burn — personalised to your stride length and body weight.

How It Works

The conversion is straightforward: distance is simply the number of steps multiplied by your stride length. Calories use a standard metabolic approximation for flat, moderate-pace walking.

where $N$ is step count, $S$ is stride length in metres, $W$ is body weight in kg, and $D$ is distance in metres. The constant 0.00057 approximates the metabolic cost of walking on flat ground (MET ~3.5, converted to kcal/kg/m).

Average Stride Length

If you haven't measured your own stride, use these estimates:

Stride length increases with walking pace — a brisk walk may add 10–15% over a leisurely stroll. For accurate calorie counting, measuring your own stride is worth the two minutes it takes.

The 10,000-Step Goal

The popular 10,000-step target originated in Japan in the 1960s (万歩計, "10,000-step meter") and was later endorsed by health agencies worldwide. At an average stride of 0.762 m, 10,000 steps equals approximately 7.6 km4.7 miles and burns around 300 kcal for a 70 kg person. The US CDC recommends 150 minutes of moderate walking per week — 10,000 steps per day typically satisfies this.
