BMI, BMR & daily energy
How BMI, BMR and TDEE are calculated
BMI = kg ÷ metres². Adult categories use Taiwan HPA cutoffs: 18.5, 24 and 27. BMR uses Mifflin–St Jeor; TDEE multiplies BMR by the selected activity factor.
Taiwan and WHO comparison
Taiwan defines overweight from BMI 24. A commonly used WHO reference starts overweight at BMI 25. This calculator uses the Taiwan adult standard by default.
These are screening estimates, not a diagnosis or a substitute for medical care. Athletes, pregnancy, oedema, ageing, medication and illness can make formula estimates less accurate.

The tool exposes the main controls needed to create, inspect or transform the selected content. Results can be copied or downloaded for use in documents, web pages, design files, development work and everyday file preparation without installing a desktop utility.
For dependable results, start with a valid source file, confirm the preview or status message, and open the downloaded copy before replacing the original. Large page counts, very high-resolution images and complex documents require more device memory and may take longer than small files, even though the controls and output steps remain the same.
