Steps to Distance Calculator

Converts a pedometer step count into distance using a measured stride length, or a walking stride estimated from height (stride ≈ 0.414 × height).

When to use

You have a daily step count and want to know the distance walked in kilometres and miles, or the number of steps in a kilometre or mile.

Do not use when: The steps were mostly running (running strides are considerably longer; enter a measured stride_length_m instead) or you need calories (use calories-burned with the walking activity).

Formula

stride_length_m = 0.414 × height_cm / 100 (unless measured); distance_m = steps × stride_length_m; distance_km = distance_m / 1000; distance_mi = distance_km / 1.609344

Step length at normal walking speed is about 41–43 % of height, which gives roughly 2,000–2,500 steps per mile for adults; Hoeger et al. (2008) measured similar counts and showed step length increases with speed. Measure 10 steps and divide for a personal value.

Inputs

Parameter	Type	Unit	Required	Description
`steps`	integer	steps	yes	Number of steps taken. Range: ≥ 0, ≤ 10000000
`height_cm`	number	cm	no	Height, used to estimate a walking stride of 0.414 × height when stride_length_m is not given. Range: ≥ 50, ≤ 300
`stride_length_m`	number	m	no	Measured length of one step in metres (heel to heel). Overrides the height estimate. Range: > 0, ≤ 3

Outputs

Output	Type	Unit	Description
`distance_km`	number	km	Distance walked in kilometres.
`distance_mi`	number	mi	Distance walked in miles.
`distance_m`	number	m	Distance walked in metres.
`stride_length_m`	number	m	Step length applied (measured or 0.414 × height).
`steps_per_km`	number	steps/km	1000 / stride_length_m.
`steps_per_mile`	number	steps/mi	1609.344 / stride_length_m.

Example

10,000 steps, 175 cm tall: {"steps":10000,"height_cm":175} → {"stride_length_m":0.725,"distance_km":7.245,"distance_mi":4.502,"distance_m":7245,"steps_per_km":1380}

8,000 steps, measured stride 0.80 m: {"steps":8000,"stride_length_m":0.8} → {"distance_km":6.4,"distance_mi":3.977,"steps_per_mile":2012}

FAQ

Is 'stride' one step or two?

Here stride_length_m is the length of one step (heel of one foot to heel of the other). Some pedometers define a stride as two steps; halve such a value before entering it.

How far is 10,000 steps?

About 7–8 km (4.5–5 miles) for most adults walking, depending on height and pace.
