Estimate gross calories during active Tai Chi practice from body weight, duration, and a named activity reference: general, seated light practice, or Yang style.

Estimate gross energy during active Tai Chi practice using the general 3.3-MET reference. Gross energy includes resting metabolism; exclude breaks from your active time.

Choose a named source activity. Sitting means seated, light-effort practice. Yang style is a specific activity reference, not a faster-flow setting. These are population estimates, not a personal pace scale.

Changing units converts your value. Maximum: 1,000 kg. This is a software limit, not an accuracy range.

Exclude breaks. Changing units converts the duration. Maximum: 1,440 minutes. This is a software limit.

Tai Chi Calories Burned Formula

Use the formula below to estimate gross calories during active practice, including resting metabolism. Exclude breaks from the entered time. Activity references come from the 2024 Adult Compendium of Physical Activities for ages 19–59; they are population estimates, not precise personal calorie measurements.

C = MET × 3.5 × BW / 200 × T

Variables:

  • C = estimated gross calories during active practice
  • BW = body weight in kilograms (lb × 0.45359237)
  • T = active practice time in minutes (hours × 60)
  • MET = the named Tai Chi activity reference

Choose a practice reference and use either pounds or kilograms, with minutes or hours. General Tai Chi/Qi Gong uses 3.3 MET by default. The other references describe specific activities, not a generic gentle-to-fast pace scale.

  • Tai Chi/Qi Gong, sitting, light effort: 1.5 MET (15672). This requires seated practice; it does not describe every gentle or therapeutic standing session.
  • Tai Chi/Qi Gong, general: 3.3 MET (15670).
  • Tai Chi Chuan, Yang style: 6.0 MET (15674). This is a specific named style, not a faster-flow setting for arbitrary movements.

How Many Calories Does Tai Chi Burn?

The table below shows estimated gross calories for active general Tai Chi/Qi Gong practice at 3.3 MET. Calculations use the listed pound weights before rounding to whole calories.

Body Weight30 Minutes60 Minutes
120 lb94 calories189 calories
150 lb118 calories236 calories
180 lb141 calories283 calories
200 lb157 calories314 calories

How to Calculate Calories Burned Doing Tai Chi

  1. Enter your body weight.
  2. Enter active practice time in minutes or hours, excluding breaks.
  3. Choose the named practice reference and your weight and time units. Changing units converts the entered value.
  4. Click Calculate, or use MET × 3.5 × body weight in kg ÷ 200 × active minutes to estimate gross calories.

Example: For a 150 lb person practicing general Tai Chi/Qi Gong for 45 active minutes, estimated gross energy is 176.82 calories: 3.3 × 3.5 × (150 × 0.45359237) ÷ 200 × 45 ≈ 176.82.

What Changes the Calorie Burn?

  • Body weight: This model scales the estimate with entered weight at the same activity reference and active duration.
  • Session length: More active practice time increases the modeled total; break time is excluded.
  • Practice reference: General, seated light practice, and Yang style use different source activities. They do not calibrate an individual pace or every therapeutic session.
  • Movement depth: Stance depth, arm movements, and pauses can affect actual energy use. This calculator does not measure or individually adjust those differences.

What Is Tai Chi?

Tai Chi is a low-impact movement practice built around slow sequences, balance, posture, and controlled breathing. It is commonly used for mobility, coordination, joint-friendly exercise, and steady full-body movement.
