What it does

Estimates the calories used by a walk or run from the minutes and your weight with published MET values. It is an estimate and shows its working.

  1. Choose the activity and enter the minutes.
  2. Enter your body weight and choose pounds or kilograms.
  3. Read the estimate first, then the working with the MET value.

Assumptions

  • It is an estimate. Fitness, body size, terrain, wind and technique change the real figure.
  • The MET values are averages for groups of people.
  • It does not say how many calories you should use or eat.

Printed from oneclickanswers.com. Results are estimates based on what was entered; see the assumptions above.

How it works

Calories = MET x weight in kilograms x hours. A MET is the activity energy cost relative to rest, about 1 kcal per kilogram per hour.

Walking at 3.0 mph is 3.5 METs (Physical Activity Guidelines for Americans, 2nd edition). For 30 minutes at 160 pounds (72.6 kg): 3.5 x 72.6 x 0.5 = 127.0 kcal, which the page rounds to about 125.

The four MET values are the ones the Physical Activity Guidelines state for a speed: walking at 2.0 and 3.0 mph, running at 6.0 mph, and 13.4 or more for running a 7.5-minute mile. Nothing between them is guessed. One MET is taken as about 1 kcal per kilogram per hour, the usual rule of thumb.

Formulas and details
  • kcal = MET x kilograms x hours.
  • kilograms = pounds / 2.2046226.

Assumptions

  • It is an estimate. Fitness, body size, terrain, wind and technique change the real figure.
  • The MET values are averages for groups of people.
  • It does not say how many calories you should use or eat.

Example

Input: The starting values already in the form

Result: Walking at 3.0 mph for 30 minutes uses an estimated 125 calories for a 160-pound person. An estimate: the real figure depends on the person, the intensity, fitness and conditions.

Questions

Is a fitness watch more accurate?

It may use more of your own data, but it is also an estimate. Both are best read as rough guides.

Why only four speeds?

Those are the only speeds for which the U.S. Physical Activity Guidelines state a MET value. Other speeds would mean guessing, so they are not offered.
