Key takeaways
  1. One conventional MET equals 3.5 milliliters of oxygen per kilogram per minute. MET value equals VO2 divided by 3.5.
  2. The conventional MET can misrepresent resting metabolism for some people. A calorie estimate based on METs should be treated as approximate.
  3. The calculation runs in your browser. Nothing you enter is stored, sent, or transmitted.

What does this exercise met calculator tell you?

Convert relative oxygen uptake into metabolic equivalents and optionally estimate calories for a session.

One conventional MET equals 3.5 milliliters of oxygen per kilogram per minute. MET value equals VO2 divided by 3.5.

How to use the result

Use the result as a consistent planning number. Record the inputs with the answer so a later comparison uses the same method.

Recalculate when the underlying inputs change. Avoid comparing results created with different units, measurement methods, or machine settings.

Where the number stops being useful

The conventional MET can misrepresent resting metabolism for some people. A calorie estimate based on METs should be treated as approximate.

What is the catch?

Check every entry and keep units consistent. When an input is uncertain, calculate a reasonable high and low case so you can see how much the answer depends on that number.

Common questions

What is one MET?

It is the conventional energy or oxygen use while sitting quietly, represented as 3.5 milliliters per kilogram per minute.

Do I need to enter body weight?

No. Weight and time are only needed for the optional calorie estimate.
