Whenever you do a workout or some type of physical activity, it can be helpful to know how many calories you are burning during the workout.
The type of exercise that you perform, the intensity at which you are working out, and your body weight will primarily determine the number of calories that you burn per minute.
One of the ways to rank the relative intensity of any type of physical activity and calculate the number of calories burned is by using METs, which stands for metabolic equivalents.
But, what are METs? What are the METs values for common types of exercise? In this article, we will discuss what is meant by METs, how to calculate METs, and the METs values for different types of workouts.
We will cover:
- What Are METs?
- How Are METs Calculated, and How Do You Calculate Energy Expenditure from METs?
- Examples of METs for Various Types of Exercise
- Why Are METs Important In Your Workout Routine?
Let’s dive in!
What Are METs?
METs, which is short for metabolic equivalents, is essentially a ranking or numerical system that denotes the ratio of the metabolic cost or energy expenditure of an activity or type of exercise relative to sitting quietly at rest.
The METs values for an activity are based on a scale. Sitting at rest is set at the baseline of the scale, so it has a metabolic equivalent of 1 (1 MET). This is essentially your resting metabolic rate, or RMR, which is just slightly above your basal metabolic rate (BMR).
Every other type of physical activity or exercise is scored or assigned a metabolic equivalent relative to the resting metabolic rate.
So, an activity with a METs value of 3.0 requires three times more energy per minute (or burns three times the calories per minute) than sitting at rest.If you do a vigorous activity that has a METs value of 8.5, you are exerting 8.5 times more energy per minute than you would be at rest.
The higher the METs score for an activity, the more calories you will burn doing that activity per minute.
How Are METs Calculated, and How Do You Calculate Energy Expenditure from METs?
METs are calculated based on your oxygen consumption for an activity relative to rest. Your resting metabolic rate (1 MET) is approximately equal to 3.5 mL of oxygen consumed per kilogram of body weight per minute.
The METs values for other activities have mainly been determined by testing oxygen consumption while performing the task in an exercise physiology lab.
From the METs score, you can calculate your energy expenditure or the number of calories you burn per minute doing the activity using the following equation:
Calories burned per minute = (METs value x 3.5 x body weight in kg) / 200
For example, if you weigh 165 pounds (75 kg) and run 6 miles per hour or 9.66 kph, which is equal to 9.8 METS: 9.8 METS x 3.5 x 75 / 200 = 12.86 calories per minute.
Then, if you run for 30 minutes, you multiply the number of calories burned per minute by 30 minutes = 12.86 x 30 = 386 calories.
In fact, you can use our Calories Burned Per Activity Calculator for free to calculate calories burned for over 800 activities, which uses the calories burned per minute formula above.

Why Are METs Important In Your Workout Routine?
The metabolic equivalents, or METs values, for different activities can be divided into categories of exercise intensity.
In other words, there is a range of METs for low-intensity, moderate-intensity, and vigorous-intensity, respectively.
The reason this is important or can be valuable information is that it can help you determine whether you are doing enough exercise per week based on the intensity of your workouts to satisfy the guidelines for physical activity for adults.
Using the METs for the types of workouts you choose to do can therefore help you determine whether you are racking up minutes of “moderate-intensity exercise“ or “vigorous-intensity exercise” when you work out.
According to the Department of Health and Human Services, light-intensity activity is any activity that is 3.0 METs or less. Moderate-intensity activity spans from 3.0-6.0 METs, while vigorous-intensity activity is anything at or above 6.0 METs.
Overall, once you understand the meaning of a metabolic equivalent and have some familiarity with how to calculate calories burned based on METs, using them to help quantify and categorize the intensity of the types of physical activity and exercise you choose to do can be a useful way to keep track of the amount of activity you are doing per week.
Knowing the METs scores for various common types of exercise can also help you make decisions about the most efficient calorie-burning workouts to do when you are short on time or how to space out and schedule different types of exercise on your training plan throughout the week based on the intensity or METs level.
