Steps to Km/Miles & Calories Calculator
Steps to distance and back, with walking time, calories and what research found on steps.
Your step length
Walk a distance you know at your usual pace and count every step, starting with the first foot that moves.
Uses the average step-to-height ratio measured in the CADENCE-Adults study at your cadence. Measuring is more accurate.
Calories and daily steps (optional)

About the Steps to Km/Miles & Calories Calculator
A step count only becomes a distance once you know how long your steps are. Enter your steps (or a distance) and your step length — measured by counting your steps over a known distance, typed in from your fitness tracker, or estimated from your height — and this calculator gives the distance in km and miles, how many steps make a km or a mile, and how long the walk takes at your pace.
From your cadence (steps per minute) it estimates the intensity in METs using the averages measured in the CADENCE-Adults study, and with your weight the calories the walk used. It also shows where your daily total sits in a pooled analysis of daily steps and mortality (15 cohorts, 47,471 adults). Everything is calculated in your browser.
How to use it
- Choose Steps → distance or Distance → steps and enter the number of steps or the distance in km, miles or metres.
- Pick how to set your step length: Measure it (walk a known distance such as 20 m or a 400 m track lap and count your steps), Enter it (the "stride length" from your tracker), or Estimate from height.
- Choose your walking pace — slow to very brisk — or type your own cadence (count your steps for 30 seconds and double it).
- Add your weight to see calories, and your age group to compare a daily total with the research on steps and health.
- Copy the result or download the steps-to-distance table as a CSV.
Examples
7.00 km (4.35 mi) · 1 h 28 min at 4.8 km/h · about 4.1 METs · about 415 kcal (312 kcal above resting)
Step length ≈ 73.0 cm · 1 km ≈ 1,371 steps · 1 mile ≈ 2,206 steps
Step length 71.4 cm (20 m ÷ 28 steps)
6,667 steps · 55 min at a brisk 122 steps/min
The formulas
- Distance = steps × step length. 10,000 steps × 0.70 m = 7,000 m = 7.00 km.
- Steps = distance ÷ step length. 1 km ÷ 0.70 m = 1,429 steps; 1 mile (1,609.344 m) ÷ 0.70 m = 2,299 steps.
- Walking time = steps ÷ cadence. 10,000 steps at 114 steps/min = 87.7 minutes.
- Speed = cadence × step length. 114 × 0.70 m = 79.8 m/min = 4.79 km/h.
- Calories = METs × body weight (kg) × hours, the rule of the 2024 Adult Compendium of Physical Activities (1 MET = 1 kcal per kg per hour). The result includes the energy you would have used anyway at rest; the figure above resting uses METs − 1.
- Measured step length = distance walked ÷ steps counted: 20 m ÷ 28 steps = 0.714 m.
Where the METs and the height estimate come from
In the CADENCE-Adults study (Tudor-Locke et al.), 76 adults aged 21–40 walked 5-minute treadmill bouts from 0.5 mph upwards while their oxygen uptake was measured. Their average cadence and METs were 96 steps/min and 2.9 METs at 2 mph, 114 steps/min and 4.0 METs at 3 mph, and 129 steps/min and 6.2 METs at 4 mph. This calculator interpolates between those published averages for the cadence you choose. The authors' rounded rule of thumb: 100 steps/min is about 3 METs (moderate) and 130 steps/min about 6 METs (vigorous), with 110 ≈ 4 and 120 ≈ 5 METs.
The participants averaged 170.7 cm tall. Dividing the treadmill speed by their average cadence gives roughly the length of their average step at each speed: 0.56 m at 2 mph, 0.71 m at 3 mph and 0.83 m at 4 mph — about 33%, 41% and 49% of their height. Estimate from height scales those step lengths to your height at your cadence, because people take longer steps as they walk faster. It is a group average: measuring your own steps is more accurate.
How many steps a day?
Paluch et al. pooled 15 cohorts (47,471 adults, 3,013 deaths over a median of 7.1 years). Compared with the quarter of people taking the fewest steps (median 3,553 a day), the risk of death during follow-up was lower in the groups with medians of 5,801 (hazard ratio 0.60), 7,842 (0.55) and 10,901 steps (0.47), after adjustment. The risk kept falling with more steps until it levelled off at about 6,000–8,000 steps a day for adults aged 60 and over and 8,000–10,000 for adults under 60. Once total steps were taken into account, the links with stepping faster were weaker and less consistent.
These are associations in observational cohorts, not proof that adding steps causes the difference, and they are not a personal target from a doctor.

Limitations
- Steps vary in length: you step shorter indoors, uphill and when you stroll, and longer when you walk briskly. Measure at the pace you usually walk.
- Running steps are much longer than walking steps; measure a running step separately before converting running steps.
- METs and calories are averages for healthy adults aged 21–40 walking on a level treadmill; your own energy use can differ, and the estimates cover cadences of 60–140 steps per minute.
- Fitness trackers count some arm movements as steps and miss others, so their totals are estimates too.

Frequently asked questions
How far is 10,000 steps?
It depends on your step length: with 0.70 m steps it is 7.0 km (4.35 miles); with 0.80 m steps 8.0 km (4.97 miles). Measure your step length here for your own answer.
How do I measure my step length?
Walk a distance you know — a 20 m hallway, 100 m of a track or one 400 m lap — at your normal pace, counting every step from the first foot strike. Divide the distance by the steps: 20 m ÷ 28 steps = 71.4 cm. Repeat two or three times and use the average.
Is stride length the same as step length?
In gait research a stride is two steps (left plus right). Most fitness trackers and pedometers, though, use "stride length" for the length of one step — which is what this calculator needs.
How many steps are in a mile or a kilometre?
Divide 1,609.344 m (a mile) or 1,000 m by your step length: with 0.70 m steps a mile is about 2,299 steps and a kilometre about 1,429. In one study of 31 adults wearing a pedometer, a mile took between 1,330 and 1,996 steps depending on their pace and size.
How many calories do 10,000 steps burn?
For a 70 kg person walking 0.70 m steps at 114 steps per minute, about 415 kcal in total, of which about 312 kcal is above what they would have used at rest. Weight, pace and step length all change the answer.
What cadence counts as brisk walking?
In the CADENCE-Adults study about 100 steps per minute matched moderate intensity (3 METs) and about 130 steps per minute vigorous intensity (6 METs) for adults aged 21–40.
