Benchmark table: distance and time by step count

Distance uses stride length estimated at 41.3 percent of height: 28.5 inches at 5 foot 9, and 29.7 inches at 6 foot 0. Time is at a normal 3.0 mph pace using the 5 foot 9 distance. If your stride differs, the calculator above adjusts; the table is a reference, not a promise.

Benchmark table: calories by step count and body weight

Standard formula, flat ground: about 0.04 calories per step at 150 pounds, scaled by body weight. Real-world burn varies with pace, terrain, and the walker, which is why the calculator shows a range of plus or minus 10 percent around these figures.

Methodology, in short

Two models, both published. The standard formula estimates walking calories at about 0.04 calories per step for a 150 pound walker, scaled by your weight and adjusted for terrain. David's logged model is n=1: at 172 pounds, his maintenance intake across hundreds of logged days tracks 1,800 base calories plus 60 calories per 1,000 steps. One is a textbook estimate. The other is a lived number. The gap between them is the story.

Stride length is estimated at 41.3 percent of height and can be edited if you have measured yours.
Terrain adjustments: hills multiply the standard calorie estimate by 1.15; treadmill incline adds about 3.5 percent per point of grade.
The honest range is plus or minus 10 percent. Individual variation is real, and any calculator that hides it is selling false precision.
Watch calorie numbers are treated as unreliable here. A 2017 Stanford study found even the most accurate wrist device tested was off by an average of 27 percent on energy expenditure, and the least accurate by 93 percent.
Health context cites the July 2025 Lancet Public Health synthesis of 57 studies: 7,000 steps a day versus 2,000 was associated with a 47 percent lower risk of all-cause mortality, with benefits flattening around 8,000 to 10,000 steps.

Reference charts

The two charts the calculator's math comes from, published as citable pages. The steps to miles chart converts every count from 1,000 to 50,000 steps at six heights and corrects the 2,000 steps per mile myth. The walking pace chart converts mph to minutes per mile and cadence, and prices how long each step count takes at every pace.
