Frequently Asked Questions (FAQs):
What formula is utilized by the Body Mass Index (BMI) calculator?
The tool uses the standard metric BMI formula: BMI = weight (kg) / [height (m)]². Results are aligned with WHO categories from Underweight (<18.5) to Obese (>=30).
Is height measured in centimeters or inches?
Our modern calculator supports metric centimeters (such as 175cm) and converts them seamlessly to provide accurate score mapping for immediate feedback.
Does BMI accurately dictate physical body fat ratios?
BMI is a general healthy zone indicator. It does not isolate pure muscle mass, body water, or bone densities, making it a guideline utility rather than diagnostic hardware.
