What the Steps to Distance Calculator does
This calculator converts a step count into kilometres and miles - or a distance into the number of steps it takes - using a step length you measure yourself or one estimated from your height. Add your weight and it also estimates the calories the walk or run used, from the published MET value for your pace.
10,000 steps is 6.5 km at a 65 cm step and 8 km at an 80 cm step, and step length varies with height, pace and the way each person walks. That is why this tool asks for your height or, better, a measured step, instead of quoting one figure for everyone. The calorie figure uses the 2024 Adult Compendium of Physical Activities, the standard research reference for the energy cost of activities, and shows the sum it did. Everything is worked out in your browser; your height and weight are not sent anywhere.
How to use it
- Choose Steps → distance or Distance → steps, and enter the steps (from your phone or watch) or the distance in kilometres, miles or metres.
- Pick the activity and pace that matches the walk - from a stroll to very brisk walking, or running. This sets the MET value for calories and, if you do not give a time, the speed used to estimate it.
- Give your height (in cm or feet and inches) to estimate your step length, or choose "I measured it" and type your step in cm - or a distance you walked and the steps you counted over it.
- Add your weight in kg or pounds for a calorie estimate. Enter the minutes you walked if you know them; otherwise the time comes from your pace. Tick the box only if you want your height and weight remembered in this browser.
- Read the distance, your personal steps per kilometre and mile, and the calorie estimate. The table shows what common step goals mean for you.
Reading the results
"Your steps per km" is the most useful number to keep: at a 70.6 cm step it is about 1,417 steps per kilometre and 2,281 per mile. Divide any step count by it to get your distance.
Gross calories are the total energy used during the walk, including what your body would have used resting. Net calories subtract the resting part (1 MET) and are the extra energy the walking itself cost - the figure to compare with food if you are tracking intake.
A step is one foot landing, from heel to heel of the other foot. A stride, as some watches use the word, is two steps. If your device says "stride length", check which one it means before typing it in.
Worked example: 10,000 steps for a 170 cm man walking briskly
With no measured step, the estimate is 170 cm × 0.415 = 70.55 cm a step. 10,000 steps × 0.7055 m = 7,055 m, which is 7.06 km, or 7,055 ÷ 1,609.344 = 4.38 miles. His steps per kilometre are 1,000 ÷ 0.7055 = 1,417.
Brisk walking at 3.5 to 3.9 mph has a MET value of 4.8 in the 2024 Compendium. At a representative 3.7 mph (5.95 km/h), 7.055 km takes 7.055 ÷ 5.95 = 1.185 hours, about 1 h 11 min. Weighing 70 kg, he uses 4.8 × 70 × 1.185 = 398 kcal in total, of which (4.8 − 1) × 70 × 1.185 = 315 kcal is above resting.
If he counts 137 steps over a measured 100 m, his real step is 73.0 cm and the same 10,000 steps are 7.30 km - a 3.5% difference that matters over a week of walking.
Formulas and scoring rules
- Distance from steps
distance = steps × step length- Steps for a distance
steps = distance ÷ step length; steps per km = 1,000 ÷ step length (m); steps per mile = 1,609.344 ÷ step length (m)- Step length estimated from height (walking)
step = height × 0.415 (men), × 0.413 (women), × 0.414 (not stated)A pedometer convention for ordinary walking, not a published standard. Not used for running.- Step length from a measured walk
step = distance walked ÷ steps counted- Running step from cadence
step = speed (m/min) ÷ cadence (steps/min)- Calories
gross kcal = MET × weight (kg) × hours; net kcal = (MET − 1) × weight (kg) × hoursUses the Compendium convention 1 MET ≈ 1 kcal per kg per hour; time = minutes entered, or steps ÷ cadence, or distance ÷ the pace band's speed.
Measuring your own step length
Find a distance you know: 100 m on a running track, a measured stretch of pavement, or the length of a football pitch. Walk it at your normal pace, counting each time a foot lands, and divide the distance by the count. Do it twice and average. A step measured this way is far more reliable than any formula, and once you have it, enter it under "I measured it" - or tick the box to have this browser remember it.
Your step gets longer when you walk faster and shorter on hills, in crowds and on rough ground, so a phone that counts steps all day will rarely match a single measured walk exactly.
Where the MET values come from
The Compendium of Physical Activities, first published in 1993 and updated in 2000, 2011 and 2024, lists the energy cost of hundreds of activities as METs - multiples of the energy used sitting quietly. The 2024 adult edition gives, for level walking on a firm surface, 2.8 MET at 2.0-2.4 mph, 3.8 MET at 2.8-3.4 mph, 4.8 MET at 3.5-3.9 mph and 5.5 MET at 4.0-4.4 mph. These are averages for adults aged 19 to 59; the authors note that individual values differ.
Limitations: what the result does not prove
- Both the step estimate and the calories are averages. A measured step improves the distance a lot; the calorie figure can still be well off for a particular person.
- MET values are for level, firm ground without a load. Hills, stairs, sand, a heavy bag or pushing a buggy all raise the energy cost.
- This is not medical or dietary advice. If you have a health condition, ask a doctor or physiotherapist what activity level suits you.
- Step counts themselves are estimates: phones and watches miss or add steps, especially at slow speeds or when carried in a bag.

Frequently asked questions
How many km is 10,000 steps?
About 7 km for an average-height adult, but it depends on your step. At a 65 cm step it is 6.5 km, at 75 cm it is 7.5 km. Enter your height or measured step to get your own figure; a 170 cm man walking normally covers about 7.06 km (4.38 miles).
How many steps are in a kilometre?
Divide 1,000 by your step length in metres. With a 70 cm step that is about 1,429 steps; with a 65 cm step about 1,538. Running steps are longer, so the count per kilometre falls.
How many steps are in a mile?
Divide 1,609.344 by your step length in metres. A 70 cm step gives about 2,299 steps per mile and a 76 cm step about 2,118. The often-quoted figure of 2,000 steps per mile fits a step of about 80 cm, which is longer than most people's walking step.
How many calories do 10,000 steps burn?
It depends on your weight, pace and step length. A 70 kg person walking 7.06 km briskly at 4.8 MET uses about 398 kcal in total, or about 315 kcal above resting. A lighter person, or a slower walk, uses fewer; add your weight and pace to see yours.
How do I calculate my stride length from my height?
A common estimate for walking is height × 0.415 for men and × 0.413 for women, giving one step - heel to heel of the other foot. A stride (two steps) is double. It is only a rule of thumb; counting your steps over a known distance gives a much better figure.
Is a step the same as a stride?
Not always. A step is the distance from one foot landing to the other foot landing. A stride is usually two steps - the same foot landing twice. Some fitness apps say "stride length" when they mean step length, so check whether the number is about half or about equal to your height × 0.41.
Why does my phone show a different distance?
Phones and watches use their own step-length estimate, usually from the height in your profile, and sometimes GPS. If your profile height is wrong or your step is longer or shorter than average, the distance shifts. Measure your step and compare - and update the step length in the app if it allows it.
