How We Compare
3,000 steps × 0.74 m ≈ 2.2 km. 5,000 × 0.74 m ≈ 3.7 km.
Difference: 2,000 steps ≈ 1.5 km ≈ 18 minutes of walking.
Mortality-risk reduction begins around 2,500 steps and steepens sharply through 5,000.
Sedentary vs low active
Under 3,000/day is 'sedentary' (Tudor-Locke). 3,000–5,000 is 'low active'. Even the jump from 3k to 4k is associated with a meaningful drop in all-cause mortality risk.
Safe progression
Add 500 steps/week. Six weeks moves you from 3,000 to 6,000 — a huge health upgrade with negligible injury risk if shoes are decent.
Where 3,000 is enough
Recovery days, illness, injury return, or as a floor for a very hot/cold day. It's a valid maintenance minimum.

MET 3.8 moderate. Stride 0.74 m.
How we calculate this (worked example)
Every figure on this page is produced by the same calculation engine as the calculator above — no hardcoded numbers. Here is the full arithmeticfor 10,000 steps at 70 kg (154 lbs), moderate pace, flat ground.
- Distance: 10,000 steps × 0.74 m ÷ 1,000 = 7.40 km (4.60 miles)
- Walking time: 7.40 km ÷ 5 km/h × 60 = 1h 29m (89 minutes)
- Calories: 3.8 MET × 70 kg × 3.5 ÷ 200 × 89 min = 413 kcal
- Per step: 413 kcal ÷ 10,000 steps = 0.041 kcal per step
10,000 steps by body weight
| Body weight | Distance | Walking time | Calories burned |
|---|---|---|---|
| 55 kg (121 lbs) | 7.40 km (4.60 mi) | 1h 29m | 325 kcal |
| 70 kg (154 lbs) | 7.40 km (4.60 mi) | 1h 29m | 413 kcal |
| 85 kg (187 lbs) | 7.40 km (4.60 mi) | 1h 29m | 502 kcal |
| 100 kg (220 lbs) | 7.40 km (4.60 mi) | 1h 29m | 591 kcal |
Distance and time are identical across weights (7.4 km at 0.74 m stride) because only energy expenditure scales with body mass.
Definitions
- Step
- One single footfall. Two steps make one full stride cycle, so a pedometer counting 10,000 steps records 5,000 complete left-right cycles.
- Stride length
- The horizontal distance covered by one step, measured heel-to-heel. We use 0.74 m (2.43 ft) as the average adult value, or 0.415 × height in cm for men and 0.413 × height for women.
- Walking distance
- Steps × stride length. Distance in kilometres = (steps × stride in metres) ÷ 1,000; miles = kilometres × 0.621371.
- Calories burned
- Total (gross) energy expenditure estimated with the MET equation: kcal = MET × weight (kg) × 3.5 ÷ 200 × minutes. Unmodified level walking at 3.1 mph (5 km/h) uses 3.8 MET from the 2024 Adult Compendium, code 17190, matching the walking planner and calorie comparison. The equation's 3.5 is the oxygen-conversion constant, not the walking MET. Distinct terrain, incline and fitness options retain their separately scoped legacy heuristics.
- Walking time
- Distance ÷ walking speed. At the 5 km/h baseline, one kilometre takes 12 minutes and one mile takes about 19 minutes.
- Cadence
- Steps per minute. A moderate 5 km/h pace corresponds to roughly 100–110 steps per minute; brisk walking is 120+ steps per minute.
Assumptions and rounding rules
| Parameter | Default | Rule |
|---|---|---|
| Stride length | 0.74 m (2.43 ft) | Average adult; overridden by your height or entered stride |
| Walking pace | 5 km/h (3.1 mph) | Moderate, flat ground; reduced 20% on hills and 30% on trails |
| MET value | 3.80 | Flat terrain, moderate fitness; +0.1 MET per 1% incline |
| Body weight | 70 kg (154 lbs) | Reference weight for examples; your input replaces it |
| Distance rounding | 2 decimals (km and miles) | Rounded for display only — full precision is used in the maths |
| Calorie rounding | Nearest whole kcal | Rounded at the last step, never mid-calculation |
| Step rounding | Nearest whole step | Reverse calculations round to the nearest integer step |
Limitations
- All results are estimates, not measurements. MET-based calorie models typically fall within ±10–20% of indirect calorimetry for an individual.
- Individual differences in gait efficiency, age, body composition and fitness change actual energy cost at the same speed.
- Terrain, surface softness, wind and altitude are only partly captured by the terrain and incline settings.
- Stride length varies with pace, footwear and fatigue; a single average stride cannot represent a whole walk.
- Pedometers and phone accelerometers miscount steps by roughly 5–15%, especially at slow speeds or when carried in a bag.
- Figures describe total (gross) energy during the walk, including resting metabolism. Activity-related (active) energy subtracts 1 MET of resting expenditure for the same duration. Gross and active calories are two views of the same walk, not amounts to add together; do not count the resting portion again in a daily energy budget.
Method: stride-based distance plus the MET equation from the Compendium of Physical Activities (Ainsworth et al.). Results are estimates — see our estimation disclaimer.
Key takeaway
3,000 steps is a valid floor; 5,000 is the first meaningful target. Progress 500 steps/week and you'll hit 5,000 in a month.

Real-Life Scenarios
The recovering post-surgical walker
3,000 for 2–3 weeks, then 500/week. Slow beats aggressive here.
The retired beginner
3,000 baseline, aim for 5,000 by week 6. Focus on daylight + fresh air, not pace.
The re-committed exerciser
3,000 is a 'don't miss' minimum on tough days. Aim for 6–7k average across the week.
In summary: 3,000 steps is a valid floor; 5,000 is the first meaningful target. Progress 500 steps/week and you'll hit 5,000 in a month.
