How it works
Enter the requested values, check the units, then run the Adult BMI Calculator for a copyable informational estimate.
The tool works by CDC adult BMI screening calculation; BMI is not a diagnosis and adult categories do not apply to children. The result is a general estimate that cannot account for every individual factor and does not replace a clinician. Inputs stay in the browser.
Examples
Practical example
A 70 kg, 175 cm adult produces BMI 22.9.
