Body weight
At the same MET value and duration, the equation estimates a greater energy cost for a heavier person.
A 70 kg person burns about 250 calories in 30 minutes of moderate tennis.
Your estimate changes with playing format, body weight and time.
“Kibora is the first one that actually feels effortless.”
“Finally a food app I don’t hate using. That’s honestly the biggest win.”
“Snapping a pic instead of digging through menus and typing everything out has actually made me stick with tracking for once.”
Choose the playing format that best matches your session. Leave out long breaks, time waiting for a court and time spent watching.

Singles usually involves more court coverage per player than doubles. Non-game practice uses a separate preset.

Technique, fitness and physiology can make actual expenditure differ from the reference estimate.
These estimates use activity-specific MET values from the 2024 Adult Compendium of Physical Activities.
Hitting balls: 5 MET (code 15695); Doubles: 6 MET (code 15680); General tennis: 6.8 MET (code 15675); Singles: 8 MET (code 15690).
The Compendium also lists another doubles entry at 4.5 MET. This calculator explicitly uses code 15680 at 6.0 MET; it is not a universal value for every doubles session.
Estimated kcal = MET × 3.5 × body weight in kilograms ÷ 200 × duration in minutes.
The table and calculator round to whole kcal. These are total (gross) calories, including energy the body would use at rest during the same interval.

The Adult Compendium provides population reference values, principally for adults aged 19–59. Effort varies within real sessions, and the result is not an individualized measurement.
For 70 kg body weight, the general tennis reference estimates about 250 total calories in 30 minutes. Choose the activity preset that matches your session.
At 70 kg, the presets on this page range from about 368 to 588 total calories per hour. Actual effort can differ.
These are total calories during the activity, including resting energy. A watch showing only active calories may display a lower number.
