Hitung BMI

Kalkulator BMI (Indeks Massa Tubuh) menghitung status berat badan Anda secara instan berdasarkan tinggi dan berat badan. Hasilnya menunjukkan apakah Anda termasuk kurus, berat badan normal, kelebihan berat badan, atau obesitas — sesuai pedoman Organisasi Kesehatan Dunia. Meskipun BMI tidak membedakan massa otot dan lemak, alat ini tetap menjadi instrumen skrining yang diakui secara luas.

What is BMI and how is it calculated?

Body Mass Index is calculated by dividing your weight in kilograms by the square of your height in metres: BMI = kg ÷ m². The WHO defines four categories: Underweight (below 18.5), Normal (18.5–24.9), Overweight (25–29.9) and Obese (30 and above). The formula was developed by Belgian mathematician Adolphe Quetelet in 1832 and remains the most widely used population-level screening tool endorsed by the World Health Organization, the NHS and the CDC. For children and teenagers, age- and sex-specific percentile charts are used instead of adult thresholds.

Why BMI alone is not enough

BMI does not distinguish between fat mass and lean muscle mass, which means a muscular athlete may register as "overweight" while a sedentary person with excess visceral fat may score in the "normal" range. For a more complete picture, doctors combine BMI with waist circumference (risk increases above 88 cm for women and 102 cm for men), body fat percentage, and blood markers such as fasting glucose and cholesterol.
