Notes:
Because 1 MET is equal to 1 kcal / kg / hour it is relatively easy to calculate energy expenditure of different physical activities. Using the formula above, you can estimate the energy expenditure value for any activity as long as you know the METS.
Note: The calculation only works with weight in kilograms. To get kilograms from pounds divide pounds by 2.2. The calculation also requires that time be in hours. If the activity is only 15 minutes, you would use .25 hours.
