Calculate a height-to-weight screening measure.

What does this result mean?

BMI means body mass index, a calculation comparing weight with height.

Use it as one general height-to-weight screening value, interpreted with its limits in mind.

What can’t this calculator tell me?

BMI does not directly measure body fat or muscle and cannot diagnose health. Adult screening categories are shown only from age 20.

How is it calculated?

Weight in kilograms divided by height in metres squared. Screening labels follow CDC adult categories for age 20 and older.
