How to calculate BMI
You have a weight and a height. You will read a BMI to one decimal and a band in this tab. The weight is kilograms. The height is centimetres. 70 kg and 170 cm is 24.2. The same weight with 1.70 in the centimetre box is 242214.5.
Open BMI when both numbers are above zero. The page uses kilograms and centimetres. It is not a diagnosis and it does not adjust for a child. Nothing is uploaded.

Keep the height in centimetres
70 kg and 170 cm is the pair for a BMI of 24.2. The box wants 170, not 1.70 and not a height in feet. 1.70 in the centimetre box is 1.70 cm, and the BMI becomes 242214.5.
70 kg and 170 cm is 24.2. 1.70 cm is 242214.5. Open BMI on cv.cm
The ratio stays in this tab.

Both must be above zero. 70 and 170 become 24.2. The page divides the centimetres by 100 before it squares the metres.
Read the one-decimal BMI
24.2 is the rounded line. The band is a separate line. Copy keeps both.
Read the band from the cuts
Below 18.5 is Underweight. 18.5 is Normal. 25 is Overweight. 30 is Obesity. 24.2 stays Normal. These are the adult cuts on this page, not a child's chart.
18.5 is Normal. 25 is Overweight. 30 is Obesity. Leave the medical chart alone
The page only divides two numbers and names a band. It does not see age, muscle, or a clinic. A zero or a negative number fails.
