ما هو BMI Calculator?

▾

Body Mass Index (BMI) is a screening number calculated from your weight and height. It provides a quick indicator of whether someone may be underweight, normal weight, overweight, or obese. BMI is a population-level tool — it does not diagnose individual health.

DigiCalcs delivers precision-engineered tools for engineers and STEM professionals.

كيفية BMI Calculator

▾

1Measure weight in kg and height in metres

BMI limitations

BMI does not distinguish muscle from fat. Heavily muscled athletes often show "overweight" BMIs despite low body fat. Body composition tests (DEXA, hydrostatic) are more accurate.

BMI for children

Children use BMI-for-age percentile charts, not the adult categories. A child's BMI is healthy if between the 5th and 85th percentile for their age and sex.

BMI Categories (WHO Adult Standards)

▾

BMI Range	Category	Health risk
< 16.0	Severely underweight	Very high
16.0 – 18.4	Underweight	High
18.5 – 24.9	Normal / Healthy weight	Low
25.0 – 29.9	Overweight	Moderate
30.0 – 34.9	Obese Class I	High
35.0 – 39.9	Obese Class II	Very high
≥ 40.0	Obese Class III (morbid)	Extremely high

نصيحة احترافية

Waist-to-height ratio (waist ÷ height < 0.5) is considered by many researchers to be a better single-number health predictor than BMI.

هل تعلم؟

BMI was invented by Belgian mathematician Adolphe Quetelet in the 1830s as a statistical tool for studying populations — he never intended it to be used to assess individual health.
