Clinic forms and fitness apps still show BMI because it is two numbers almost everyone has. You enter weight in kilograms and height in centimeters; the page returns the index and a category label. Useful for orienting a conversation, not for replacing how you actually feel or what your clinician measures.
Muscle, bone density, pregnancy, and age all bend what the number means. Treat the output as a rough coordinate on a chart, not a verdict.
BMI at 70 kg and 175 cm matches the defaults—people still punch the same figures into a second app to see if the category matches.
Units and the label on the screen
This form expects metric fields. If your scale shows pounds and your doorway was measured in feet and inches, convert before you paste—154 pounds in kilograms and 69 inches in centimeters are the sort of side trips that prevent a nonsense index.
Movement planning sometimes sits next to BMI on the same dashboard—distance from 8,000 steps—different question, same afternoon.
- Planning estimate only, not medical advice.
- Category bands are generic; sport and pregnancy break the story.
- Keep height and weight beside the BMI if you share the number.
The BMI result context note is worth reading before you argue with a label. Ordinary reference math.
