Enter either the distance walked or the average speed (leave the other blank). Time is fixed at 6 minutes.

6 Minute Walk Test Calculator

In clinical practice, 6MWT results are usually recorded as the measured distance walked in 6 minutes; this calculator converts between distance and average speed for convenience.

Safety note: This calculator is for informational purposes only and is not medical advice or a diagnosis tool. If you have heart or lung disease, chest pain, dizziness, a history of fainting, uncontrolled blood pressure, or you’ve been advised to limit activity, consult a clinician before attempting a 6-minute walk test. Stop immediately and seek medical care if you develop chest pain, severe shortness of breath, dizziness, or feel faint. Clinical 6MWT is typically performed using a standardized course and instructions, ideally with supervision.

6 Minute Walk Test Formula

The following formula is used to calculate the distance covered in a 6 Minute Walk Test. 

D = S * T

1 Supporting clinical standard: ATS Statement: Guidelines for the Six-Minute Walk Test (2002)

Variables:

  • D is the distance covered in meters
  • S is the average speed in meters per minute
  • T is the time in minutes, which is fixed at 6 minutes for this test

To calculate the distance covered in a 6 Minute Walk Test, multiply the average speed by the time. The average speed is determined by the individual’s walking pace, and the time is fixed at 6 minutes for this test.

What is a 6 Minute Walk Test?

A 6 Minute Walk Test is a simple, non-invasive exercise test often used in clinical settings to assess a person’s functional capacity and endurance. The test measures the distance an individual can walk at their own pace on a flat, hard surface in a period of six minutes. It is commonly used to evaluate individuals with cardiovascular or pulmonary diseases, such as heart failure or chronic obstructive pulmonary disease (COPD), and to monitor the progress and effectiveness of a treatment or rehabilitation program.

How to Calculate 6 Minute Walk Test?

The following steps outline how to calculate the Distance covered in a 6 Minute Walk Test.

  1. First, determine the average speed (S) in meters per minute.
  2. Next, determine the time (T) in minutes (fixed at 6 minutes for this test).
  3. Next, gather the formula from above = D = S * T.
  4. Finally, calculate the Distance covered (D).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Average speed (S) = 90 meters per minute

Time (T) = 6 minutes

Distance (D) = 540 meters
