This Chair MET Calculator helps you estimate the metabolic equivalent of task (MET) for seated exercises performed in a chair. Whether you're doing seated leg lifts, arm circles, or gentle chair yoga, knowing the MET value allows you to calculate calories burned more accurately. Designed for seniors, office workers, and anyone with limited mobility, this tool bridges the gap between light activity and meaningful calorie tracking.
Simply select your activity type, enter your body weight, and the duration of your session. The calculator uses standard MET values from the Compendium of Physical Activities to provide a reliable estimate. Use it to plan gentle movement routines, track progress, or compare different chair-based exercises. No equipment needed — just a chair and a few minutes.

How to Use This Tool
Using the Chair MET Calculator is straightforward. First, select the activity that best matches your seated exercise from the dropdown list. Each option includes a standard MET value from the Compendium of Physical Activities. Next, enter your body weight and choose whether it's in kilograms or pounds. Then input the duration of your session — you can use minutes or hours. Click "Calculate" to see your estimated calories burned. The result also shows the MET value used, your weight in kilograms, and the duration in hours for transparency.
Tip: For the most accurate estimate, use your actual body weight and be honest about the intensity of your movements. If you're doing a mix of activities, calculate each segment separately and add the results.
Formula Explained
The calculation is based on the standard metabolic equivalent (MET) formula: Calories burned = MET × weight (kg) × duration (hours). One MET is defined as the energy cost of sitting quietly, equivalent to 1 kcal/kg/hour. When you exercise, your MET value increases proportionally to the intensity. For example, seated leg lifts have a MET of 1.8, meaning you burn 1.8 times the energy you would at rest. This formula is widely accepted in exercise physiology and used by health organizations worldwide.
Worked Examples
Example 1: A 70 kg person does seated chair yoga (MET 2.5) for 30 minutes. Calories = 2.5 × 70 × (30/60) = 2.5 × 70 × 0.5 = 87.5 kcal.
Example 2: A 150 lb person performs seated arm circles (MET 2.0) for 45 minutes. First convert weight: 150 lb × 0.4536 = 68.04 kg. Then calories = 2.0 × 68.04 × (45/60) = 2.0 × 68.04 × 0.75 = 102.1 kcal.
Common Mistakes to Avoid
- Using the wrong MET value: Selecting "seated quiet" when you're actually moving your arms and legs will underestimate calories. Be specific.
- Forgetting to convert units: If you enter weight in pounds but the formula expects kilograms, your result will be off by a factor of 2.2. Always use the unit selector correctly.
- Overestimating duration: Include only the time you're actively moving, not rest breaks. If you pause for 5 minutes, subtract that from your total.
Real-World Applications
This calculator is especially useful for older adults, office workers, and individuals recovering from injury who want to maintain an active lifestyle without standing or walking. Chair exercises can improve circulation, flexibility, and muscle tone. Tracking calories burned helps with weight management and motivation. Many physical therapists recommend chair-based routines for rehabilitation. Use this tool to quantify your effort and see how even gentle movement contributes to your daily energy expenditure.
Frequently Asked Questions
Q: Are these MET values accurate for everyone?
A: MET values are population averages. Individual metabolism, fitness level, and exact movement speed can cause variation. Use the estimate as a guideline.
Q: Can I use this for seated exercises not listed?
A: Yes. Choose the activity that most closely matches your intensity. For example, seated marching in place is similar to "vigorous arm & leg movements" (MET 2.8).
Q: How does this compare to walking?
A: Walking at 3 mph has a MET of about 3.5. Most chair exercises have lower MET values (1.3–3.0), so they burn fewer calories per minute, but they are excellent for low-impact movement.
